I found the field of Chemistry very interesting. Saw the article Additive Free Greener Synthesis of 1,2-Disubstituted Benzimidazoles Using Aqueous Extract of Acacia concinna Pods as an Efficient Surfactant Type Catalyst published in 2021.0. Safety of 3,4-Dimethoxybenzaldehyde, Reprint Addresses Gholap, SS (corresponding author), Padmashri Vikhe Patil Coll, Ahmednagar 413713, Maharashtra, India.. The CAS is 120-14-9. Through research, I have a further understanding and discovery of 3,4-Dimethoxybenzaldehyde

An efficient environmentally benign method for the synthesis of 1,2-disubstituted benzimidazole derivatives via one-pot multicomponent has been reported using aqueous extract of Acacia concinna pods as a naturally occurring surfactant type catalyst. The present surfactant medium was found superior and additive free for the condensation of o-phenylene diamine and two equivalent of aldehyde to yield 1,2-disubstituted benzimidazole derivatives in excellent yields under mild conditions. A simple, economically viable and biocompatible catalytic system suggested the possible utility of the present protocol for the large scale construction of benzimidazole derivatives.

Fenclorim is a commercial herbicide safener with fungicidal activity used for chloroacetanilide herbicides, which might be suitable as a lead compound for screening novel fungicides. However, little has been reported so far on the structure-activity relationship of fungicidal activities of fenclorim or its analogues. Here, a series of 4-chloro-6-substituted phenoxy-2-phenylpyrimidine derivatives was synthesized by a substructure splicing route using fenclorim as a lead compound. The structures of synthesized derivatives were characterized by H-1 NMR, C-13 NMR, and HRMS. Their fungicidal and herbicide safening activities were then evaluated. The results revealed that compound 11 had the best fungicidal activity against Sclerotinia sclerotiorum and Thanatephorus cucumeris, which was better than that of the control pyrimethanil. Moreover, compounds 3, 5, and 25 exhibited excellent safening activities against fresh weight, plant height, and root length, respectively. Such activities were significantly improved when compared to fenclorim. In summary, these findings look promising for the preparation of new fungicides and herbicide safeners based on the structure of fenclorim.

The copolymerization of vinyl benzyl alcohol (VBA) and carbon monoxide (CO) to give a new polyester poly(VBA-CO) has been achieved via palladium-catalyzed hydroesterification. Reaction conditions involve moderate temperatures, moderate to low CO pressures, and low catalyst loadings to give a low molar mass (M-n similar to 3-4 kg/mol) polymer as a similar to 2:1 mixture of linear to branched repeat units. The polymer molar mass increase is consistent with a step-growth polymerization mechanism, and ester yields of >97% are achieved within 24 h. However, increases in M-n cease beyond 16 h. Control experiments indicate that the degree of polymerization is limited due to a combination of side reactions such as alcoholic end-group oxidation, hydroxycarbonylation, and alcohol acetylation, which lead to the degradation of monomeric and polymeric end groups. When a less promiscuous substrate is used such as 10-undecenol, higher molar masses (M-n similar to 16 kg/mol) are achieved. This method has the potential to be a mild route to new polyester architectures with appropriate mitigation of side reactions.

Two different hydrolysis strategies, namely acid hydrolysis (pH 0 and 3) and enzyme hydrolysis (Rapidase AR2000, beta-glucosidase, 5.6 nkat/mg), and the effect of hydrolysis time on the liberation of glycosidically bound volatiles from tamarillo (Solanum beaceum Cay.), were evaluated. Free and bound volatile profiles in tamarillo were also compared. Enzymatic hydrolysis was favoured for the liberation of aldehydes, esters, and terpenes. Harsh acidic hydrolysis (pH 0) was particularly effective at releasing C-13-norisoprenoids including 3-hydroxy-beta-damascone and 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN), but those compounds cannot contribute to the pleasant odour. Moreover, the longer the duration of enzymatic hydrolysis, the higher was the concentration of alcohols, terpenes, benzenoids, ketones, and volatile phenols. On the other hand, 33 free and 49 bound volatiles were identified in tamarillo with a complementary profile: the major free volatiles were alcohols ((Z)-3-hexenol, 1-hexanol) and esters (methyl caproate, methyl butanoate and ethyl butanoate), while bound volatile compounds showed higher concentrations of benzenoids (benzyl alcohol and phenylethyl alcohol) and terpenes, including prenol, linalool and alpha-terpineol. Many glycosidically bound volatiles are available as aroma reservoirs in tamarillo, and to liberate these compounds during tamarillo-based product development, attention should be given to hydrolysis strategies and incubation time.

High yield 3-hydroxy benzaldehyde-N-methyl 4-stilbazolium tosylate (3-HBST) was synthesized by optimizing the reaction temperature. High-quality bulk crystals of 3-HBST were grown by slow evaporation technique and spontaneous nucleation method, respectively. The crystal structure of 3-HBST was determined by single crystal X-ray diffraction (XRD) technique and belongs to monoclinic system. The defects of the 3-HBST crystals were observed by the synchrotron radiation X-ray topography. 3-HBST crystal remains stable until 305 degrees C, with a melting point of 214.1 degrees C from the TG-DTG and DSC techniques. The dielectric constant of 3-HBST crystal was also studied. The grown crystal had good optical transparency and the optical transmittance was investigated by UV-vis-NIR spectral analysis. Photoluminescence (PL) indicated green emission occurred at 478 nm. Based on the growth technical analysis and performance parameters measurements, 3-HBST crystal was verified to be a promising organic nonlinear optical crystal.

Approximately 60% of human cancers exhibit enhanced activity of ERK1 and ERK2, reflecting their multiple roles in tumor initiation and progression. Acquired drug resistance, especially mechanisms associated with the reactivation of the MAPK (RAF/MEK/ERK) pathway represent a major challenge to current treatments of melanoma and several other cancers. Recently, targeting ERK has evolved as a potentially attractive strategy to overcome this resistance. Herein, we report the design and synthesis of novel series of fused naphthofuro[3,2-c] quinoline-6,7,12-triones 3a-f and pyrano[3,2-c]quinoline-6,7,8,13-tetraones 5a,b and 6, as potential ERK inhibitors. New inhibitors were synthesized and identified by different spectroscopic techniques and X-ray crystallography. They were evaluated for their ability to inhibit ERK1/2 in an in vitro radioactive kinase assay. 3b and 6 inhibited ERK1 with IC50s of 0.5 and 0.19 mu M, and inhibited ERK2 with IC50s of 0.6 and 0.16 mu M respectively. Kinetic mechanism studies revealed that the inhibitors are ATP-competitive inhibitors where 6 inhibited ERK2 with a K-i of 0.09 mu M. Six of the new inhibitors were tested for their in vitro anticancer activity against the NCI-60 panel of tumor cell lines. Compound 3b and 6 were the most potent against most of the human tumor cell lines tested. Moreover, 3b and 6 inhibited the proliferation of the BRAF mutant A375 melanoma cells with IC50s of 3.7 and 0.13 mu M, respectively. In addition, they suppressed anchorage-dependent colony formation. Treatment of the A375 cell line with 3b and 6 inhibited the phosphorylation of ERK substrates p-90RSK and ELK-1 and induced apoptosis in a dose dependent manner. Finally, a molecular docking study showed the potential binding mode of 3b and 6 within the ATP catalytic binding site of ERK2.

Herein we report the generation of benzylic lithiums via an iodine-lithium exchange reaction on benzylic iodides performed in continuous flow using tBuLi as the exchange reagent. The resulting benzylic lithium species are trapped in situ by carbonyl electrophiles under Barbier conditions, resulting in benzylic secondary and tertiary alcohols. This flow procedure further allows the generation of highly reactive heterobenzylic lithium compounds, which are difficult to generate under batch conditions. A general scale-up was possible without further optimization.

Copper porphyrin-catalyzed construction of ether bond by cross-dehydrogenative coupling of sp [3] C-H bond with phenols bearing electron-withdrawing groups (EWG) was described for the first time. A broad range of substrates afforded different acetals in moderate to excellent yields with good functional group tolerance. The developed method is not only suitable for phenol substrates with ortho-directing groups, but also suitable for those phenol without ortho-directing groups. Significantly, a high turnover number (TON) up to 7300 was achieved in gram-level test. (C) 2020 Elsevier Ltd. All rights reserved.

The difficulties in the separation of products from the reaction mixture and the recovery of the organic cationic ionic liquids (OCILs) catalysts still need to be addressed. Post modification of the pyridine unit in the covalent organic framework (COF) via the formation of pyridinium salts with the chiral bromoacetate led to the chiral ionic COF with OCIL immobilized, which was utilized as a heterogeneous catalyst for asymmetric Henry reactions with high yield and excellent stereoselectivity.

Carbazole alkaloids is an important class of natural products with diverse biological functions. So, the aim of this article is to explore new chemical entities containing carbazole scaffold as potential novel cytotoxic agents based on our developed three-component indole-to-carbazole reaction. Two series of carbazole derivatives were designed and synthesized, and their in vitro cytotoxic activities against three cell lines (A875, HepG2, and MARC145) were evaluated. The results indicated that some of these carbazole derivatives exhibited significantly good cytotoxic activities against tested cell lines compared with the control 5-fluorouracil (5-FU). Especially, carbazole acylhydrazone compounds 7g and 7p displayed high inhibitory activity on cancer cells, but almost no activity on normal cells. Further analysis of induced apoptosis for potential compounds indicated that the potential antitumor agents induced cell death in A875 cells at least partly (initially) by apoptosis, which might be used as promising lead scaffold for discovery of novel carbazole-type cytotoxic agents.
