A straightforward and general method has been developed for the synthesis of chalcone derivatives by a Claisen-Schmidt reaction in the presence of PPh3/I-2 in 1,4-dioxane under reflux temperatures. With the condensation of the aromatic ketone and aldehyde occurring at non-strongly alkaline conditions, our proposed method significantly expands the range of applicable substrates, especially for groups that are unstable under alkaline conditions.

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.

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.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

Category: indole-building-block. Recently I am researching about 1,5-BENZOTHIAZEPINE DERIVATIVES; ANTICANCER; ANTIOXIDANT, Saw an article supported by the Dean’s office of College of Pharmacy and Health Sciences, Ajman University, UAE. Published in ELSEVIER in AMSTERDAM ,Authors: Shaik, AB; Bhandare, RR; Nissankararao, S; Lokesh, BVS; Shahanaaz, S; Rahman, MM. The CAS is 123-11-5.

A series of twenty new chloropyrazine conjugated benzothiazepines (22-41) have been synthesized with 58%-95% yields. The compounds were characterized by using different spectroscopic techniques including FT-IR, H-1 NMR, C-13 NMR spectroscopy and mass spectrometry. The synthesized compounds (22-41) and their precursor chalcones (2-21) were evaluated for antitubercular and cytotoxic activities. Additionally, compounds 22-41 were also tested for antimicrobial activity. Among the chalcone series (2-21), compounds 7 and 14 showed significant antitubercular activities (MICs 25.51 and 23.89 mu M, respectively), whereas among benzothiazepines (22-41), compounds 27 and 34 displayed significant antimicrobial (MICs 38.02 mu M, 19.01 mu M) and antitubercular (MIC 18.10 mu M) activities. Compounds 7 and 41 displayed cytotoxic activities with IC50 of 46.03 +/- 1 and 35.10 +/- 2 mu M respectively. All the compounds were evaluated for cytotoxic activity on normal human liver cell lines (L02) and found to be relatively less selective towards this cell line. The most active compounds identified through this study could be considered as potential leads for the development of drugs with possible antimicrobial, antitubercular, and cytotoxic activities.

This paper aimed to provide an insight into the mechanism of transdermal penetration of drug molecules with respect to their physicochemical properties, such as solubility (S), the presence of enantiomer (ET) and logarithm of octanol-water partition coefficient (log P), molecular weight (MW), and melting point (MP). Propionic acid derivatives were evaluated for their flux through full-thickness skin excised from hairless mice upon being delivered from silicone-based pressure-sensitive adhesive (PSA) matrices in the presence or absence of various enhancers. The skin fluxes of model compounds were calculated based on the data obtained using the method engaged with the diffusion cell system. The statistical design of experiments (DoE) based on the factorial approach was used to find variables that have a significant impact on the outcomes. For the prediction of skin flux, a quantitative equation was derived using the data-mining approach on the relationship between skin permeation of model compounds (similar to 125 mg/ml) and involved physicochemical variables. The most influential variables for the skin flux of propionic acid derivatives were the melting point (0.97) followed by the presence of enantiomer (0.95), molecular mass (0.93), log P values (0.86), and aqueous solubility (0.80). It was concluded that the skin flux of molecular compounds can be predicted based on the relationship between their physicochemical properties and the interaction with cofactors including additives and enhancers in the vehicles.

A composite film with multiple anti-counterfeiting features was demonstrated by superposing quantum dots (QDs) polymer matrix (film A) and cholesteric liquid crystal film (film B) together. The first-line and second-line anti-counterfeiting characteristics were successfully implemented by employing thermochromic, angular photochromic, and circularly polarized discoloration of film B, respectively. By initiatively utilizing the different relative positions between the fluorescence emission peak (lambda(em)) of film A and the central selective reflection wavelength (lambda(em)) of film B at different temperatures, which resulted in changes in the fluorescence spectra or the different presence of latent patterns, the most important third-line anti-counterfeiting feature was successfully achieved.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

The morphology and size of Co-MOF-74 were effectively controlled by adjusting the water portion in DMF-H2O mixed solvent system, and six different Co-MOF-74 samples were successfully obtained. The water content can alter the deprotonation rate of the organic ligand and then change the nucleation rate of crystal, thus regulate morphology and size of Co-MOF-74. The discrepancy of morphology and size has significant effect on texture structure of Co-MOF-74 but without changing their composition. The formation mechanism of crystal growth was proposed by studying the change of reaction solution pH value. These samples exhibit morphology and size dependent catalytic activity in toluene oxidation. The flower-like sample has the best catalytic performance with 12.1% toluene conversion and 63.8% benzaldehyde selectivity. Additionally, the influence of reaction parameters on the catalytic oxidation reaction was also examined. Rearserch on the structure-property relationship of catalyst would be useful for rationally synthesizing novel MOF in heterogeneous catalysis.

A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding Ni-II pincer carbene complex, which afforded highly enantioenriched beta-hydroxynitriles. This highly atom-economical process paves the way for exploiting inexpensive acetonitrile as a promising C2 building block in a practical synthetic toolbox for asymmetric catalysis.
