I found the field of Agriculture; Chemistry; Food Science & Technology very interesting. Saw the article Synthesis of Three Bioactive Aromatic Compounds by Introducing Polyketide Synthase Genes into Engineered Escherichia coli published in 2019. SDS of cas: 86-95-3, Reprint Addresses Ahn, JH (corresponding author), Konkuk Univ, Bio Mol Informat Ctr, Dept Biosci & Biotechnol, Seoul 05029, South Korea.. The CAS is 86-95-3. Through research, I have a further understanding and discovery of 4-Hydroxyquinolin-2(1H)-one

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

Guillermo Calleja and co-workers from @urjc describe URJC-1-MOF as a new heterogeneous recyclable catalyst for c-heteroatom coupling reactions The capacity of copper-based URJC-1-MOF as a MOF catalyst in cross-coupling reactions has been evaluated, focusing on the Chan-Lam-Evans arylation-type reactions on amines and alcohols without extra additives or ligands. The extraordinary chemical and structural stability of URJC-1-MOF and its good specific surface, make this material a promising alternative to homogeneous Cu (II) catalysts for cross-coupling reactions. URJC-1-MOF showed a remarkable catalytic activity for cross-coupling C-N and C-O reactions, higher than other heterogeneous and homogeneous copper-based catalyst, such as CuO, HKUST-1, Cu-MOF-74, Cu(OAc)(2) and CuSO4.5H(2)O. Moreover, its easy recovery by simple filtration and reusability in successive runs without any loss of activity and stability, demonstrates the potential of URJC-1-MOF as an alternative catalyst for this kind of reactions in different chemical media of industrial interest.

Treatment of Ln(NO3)(3)center dot 6H(2)O (Ln = La, Ce) with an equimolar amount of 2,2′-diphenylglycine (DpgH) in ethanol afforded the corresponding hexacoordinated complexes (DpgH(+/-))(3)Ln(NO3)(3)center dot H2O (DpgH(+/-) = zwitterionic 2,2′-diphenylglycine, Ln = La (1), Ce (2)). The spectroscopic and structural features of these compounds have been investigated. Similar reactions with the related benzilic acid (BenzH(2)) were unsuccessful. The catalytic behaviour of 1 and 2 in the homo- and copolymerization of epsilon-caprolactone (epsilon-CL) and rac-lactide (r-LA) has been investigated herein. In the case of epsilon-CL, the two complexes exhibited comparable activity, allowing for complete monomer conversion under aerobic and solvent-free conditions at 150 degrees C in 24 h. With respect to the ROP of r-LA, 1 was found to be completely inactive, while only 8% conversion was achieved in the presence of 2. Liquid oligomers were isolated during epsilon-CL/r-LA copolymerization in the presence of both complexes. The catalytic activity of the pre-ligands DpgH and BenzH(2) (i.e. metal-free) was also examined. Interestingly, only BenzH(2) was found to be active, although it required a higher catalyst loading and the presence of benzyl alcohol as co-activator. (C) 2020 Elsevier B.V. All rights reserved.

A vinylation/devinylation looping system for acetaldehyde manufacturing was evaluated. Vinylation of iso-butanol with calcium carbide under solvent-free conditions was combined with hydrolysis of the resulting iso-butyl vinyl ether under slightly acidic conditions. Acetaldehyde produced by hydrolysis was collected from the reaction mixture by simple distillation, and the remaining alcohol was redirected to the vinylation step. All the inorganic co-reagents can be looped as well, and the full sequence is totally sustainable. A complete acetaldehyde manufacturing cycle was proposed on the basis of the developed procedure. The cycle was fed with calcium carbide and produced the aldehyde as a single product in a total preparative yield of 97 %. No solvents, hydrocarbons, or metal catalysts were needed to maintain the cycle. As calcium carbide in principle can be synthesized from virtually any source of carbon, the developed technology represents an excellent example of biomass and waste conversion into a valuable industrial product.

By taking advantage of benzylidene succinimides as a new class of 3C synthons, a highly diastereo- and enantioselective tandem Mannich reaction/transamidation has been established by reacting them with cyclic trifluoromethyl N-acyl ketimines. Using a Cinchona alkaloid-derived squaramide as the catalyst, the tandem reaction proceeded smoothly under mild conditions and afforded a range of F3C-containing chiral polycyclic dihydroquinazolinones with excellent results (up to 99% yield, all cases >20 : 1 dr, up to 99% ee).

A new method for the fast synthesis of diverse 4-aryl-6-cycloamino-1,3,5-triazin-2-amines was developed. The synthesis is performed under microwave irradiation in a one-pot manner from cyanoguanidine, aromatic aldehydes, and cyclic amines. Their three-component reaction in the presence of hydrochloric acid produced dihydrotriazines, which were then converted (without isolation) into the targeted compounds via aromatic dehydrogenation in the presence of alkali. The reaction tolerated various aromatic aldehydes (including heterocyclic) and cyclic amities. Crystal structures of two representative 4-aryl-6-morpholino-1,3,5-triazin-2-amines were established by X-ray crystallography. The results of preliminary biological screening identified potent antileukemic activity for 6-[3,4-dihydroisoquinolin-2(1H)-yl]-4- phenyl-1,3,5-triazin-2-amine.

The novel free radical-based cleavage of the enaminone C=C double bond is realized by using N-halosuccinimides (NXS) in the presence of benzoyl peroxide (BPO) with mild heating, enabling the tunable synthesis of alpha,alpha-dihalomethyl ketones and alpha,alpha,alpha-trihalomethyl ketones under different reaction conditions. The formation of these divergent products involving featured C=C double bond cleavage requires no any metal reagent, and represents one more practical example on the synthesis of poly halogenated methyl ketones via the functionalization of carbon-carbon bond.

A recent identification of eugenyl (allylmethoxyphenyl) esters as Anthemis segetalis Ten. (Asteraceae) essential oil constituents, accomplished by means of organic synthesis, motivated us to expand the existing synthetic library with an aim to examine the generality of structure-chromatographic property relationships within this series of volatiles. Herein, the design, synthesis, gas-chromatographic and spectral characterization of members of a library of 85 allylmethoxyphenyl esters (64 are completely new) were described. Analysis of experimentally obtained RI data showed that esters of the same acid and different allylmethoxyphenols always elute in the same order from an apolar gas chromatography (DB-5MS) column: 2-allyl-6-methoxyphenyl RI values, several quantitative structure-property relationship models were built up that correlated several easily available parameters (e.g. Wiener [WI], Balaban [BI], and molecular topological [MTI] indices) of the mentioned esters and their RI data. The generated various quantitative structure-property relationships models (equations that predict RIs of esters of different regioisomers of allylmethoxyphenols with the same acids and the ones that predict RIs of esters of different acids with the same allylmethoxyphenols) were tested on data of previously known related esters. RI data of esters of allylmethoxyphenol regioisomers could be successfully predicted based on 1D topological indices, such as the Balaban, Wiener, and molecular topological indices. Together with RI and MS data accumulated in this work, these models represent a new and simple tool for the identification of allylmethoxyphenyl esters that might potentially represent new or rare natural products.

An article CeO2 immobilized on magnetic core-shell microparticles for one-pot synthesis of imines from benzyl alcohols and anilines: Support effects for activity and stability WOS:000458596500074 published article about SELECTIVE AEROBIC OXIDATION; EFFICIENT CATALYST; TANDEM SYNTHESIS; AMINES; HYDROGENATION; NANOPARTICLES; REDUCTION; NANORODS; CERIA; HYDROAMINATION in [Long, Yu; Gao, Zekun; Qin, Jiaheng; Wu, Wei; Dong, Zhengping; Ma, Jiantai] Lanzhou Univ, State Key Lab Appl Organ Chem, Gansu Prov Engn Lab Chem Catalysis, Coll Chem & Chem Engn, Lanzhou 730000, Gansu, Peoples R China; [Wang, Peng] Liaoning Univ Technol, Sch Chem & Environm Engn, Jinzhou 121001, Peoples R China; [Zhang, Lin] 1 High Sch, Minle 734500, Gansu, Peoples R China in 2019.0, Cited 44.0.

Four types of core-shell materials with magnetic Fe3O4 microparticles as the core were prepared through different approaches using dopamine, glucose, tetrabutyl orthotitanate (TBOT), and tetraethyl orthosilicate (TEOS) as the shell precursor, respectively. CeO2 nanoparticles (NPs) was successfully immobilized onto these supports to fabricate efficient catalysts for the tandem catalytic synthesis of imines from benzyl alcohols and anilines at low temperature under air atmosphere. The as-prepared catalysts were detailedly characterized by TEM, EDX, XRD, FT-IR, XPS VSM, ICP, and CO2-TPD. Interestingly, these prepared catalysts showed higher catalytic activity than reported CeO2 catalysts. Most attractively, the catalyst with a shell of nitrogen-doped-carbon derived from dopamine exhibited the best catalytic property, and outstanding stability and recyclability in the cycle experiment. According to the XPS and CO2-TPD characterization, the enhanced performance of Fe3O4@CN@CeO2 composites can be attributed to two reasons as follows: (1) the immobilization of CeO2 improved its alkalinity at low reaction temperature, and alkalinity is beneficial to promote the oxidation of alcohols to benzaldehyde, which is the ratedetermining step for this tandem reaction; (2) the doped nitrogen generated Lewis basic site could satisfactorily stabilize Ce3+/Ce4+ pair of CeO2, which determined the catalytic activity and stability of CeO2 based catalysts for this tandem reaction. Moreover, the prepared catalysts could be facilely recovered from the reaction mixture with an external magnet. This work may provide a useful strategy for con- structing CeO2 based catalysts for green and sustainable catalysis. (C) 2018 Elsevier Inc. All rights reserved.
