Synthesis of new furan polycycles via photochemical reaction in neutral and acidic medium

New furan derivatives of o-divinylbenzenes were synthesized and their photochemical reactivity has been investigated in neutral and acidic medium. Depending of the structure of the starting materials and pH value, the new cyclization (11, 16, 20), cycloaddiotion (12, 13, endo-17, exo-18), electrocyclization (21, 22) and dimeric (15, 19) products were isolated. While photochemical investigation in neutral medium showed that the main intramolecular process is cycloaddition, in the case of acidic photochemistry, due to the protonation of the starting molecule, electrocyclization process comes to expression and formation of dihydronaphtalene products 21 and 22.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4265-16-1, help many people in the next few years.4265-16-1

Synthesis, characterization, biological activity, and 3D-QSAR studies on some novel class of pyrrole derivatives as antitubercular agents

A new series of pyrrole derivatives have been designed, synthesized, and their structures have been elucidated along with the evaluation of antitubercular activity against Mycobacterium tuberculosis H37Rv using the microplate alamar blue assay method and antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, and Escherichia coli by broth micro-dilution assay method. Structural activity relationships and 3D-QSAR analysis have been carried out by Topomer Comparative Molecular Field Analysis (CoMFA). Training set of 42 and test set of 8 active compounds were used to develop the method that showed cross-validated correlation coefficient (q 2) of 0.815, standard error of prediction of 0.36, non-cross-validated correlation coefficient (r 2) of 0.973, and standard error of estimate of 0.14 with six components. Graphical Abstract: Synthesis; spectral and 3D-QSAR studies; and antibacterial, antitubercular, and cytotoxic activities of a novel series of pyrrole derivatives are described.[Figure not available: see fulltext.]

Pyrolysis of poplar wood sawdust by TG-FTIR and Py-GC/MS

Pyrolysis of certain poplar wood sawdust (PWS) was studied by thermogravimetric analyzer coupled with Fourier transform infrared spectroscopy (TG-FTIR). Different heating rates were applied with final temperature of 950 C and about 80% loss weight was observed at the heating rate of 20-80 C/min. The temperature trend of evolving gaseous products of PWS was also investigated. Following experimental research on pyrolysis of PWS was carried out on a pyrolysis-gas-chromatography/mass spectrometry (Py-GC/MS). Associated with the analysis results of TG-FTIR and Py-GC/MS for the pyrolytic products, PWS undergoes in three consecutive stages, corresponding to (1) moisture evaporation, (2) thermal decomposition, and (3) further carbonization. The main pyrolysis sections and the maximum weight loss rates are similar for different heating rates. Carbonyls, including aldehydes and ketones, are the main volatile products, in addition to phenols, furans, benzenes, acids, and so on. As the main gaseous products, CO, CO2, CH4 are released out greatly. Furthermore, possible pyrolysis mechanisms of cellulose, hemicellulose and lignin in biomass including PWS were also proposed. All of the results and findings would help further understanding of thermal behavior of PWS and its thermo-chemical utilization for fuels and chemicals.

An improved and scale-up synthesis of 6-hydroxybenzofuran

An optimized process for the preparation of 6-hydroxybenzofuran is described. This process consists of three steps: the reaction of 2-hydroxy-4-methoxybenzaldehyde with chloroacetic acid, the formation of the 6-methoxybenzofuran in acetic anhydride, and the demethylation with sodium 1-dodecanethiolate to afford the desired product. The entire process is safe, cost effective, environmentally benign, and scalable. A production scale of over 2.6?kg product was achieved in good overall yield.

Controlled Reduction of Carboxamides to Alcohols or Amines by Zinc Hydrides

New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)? is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.

In this communication, we report the discovery of 1S (apremilast), a novel potent and orally active phosphodiesterase 4 (PDE4) and tumor necrosis factor-alpha inhibitor. The optimization of previously reported 3-(1,3-dioxo-1,3-dihydroisoindol-2-yl)-3-(3,4-dimethoxyphenyl)propionic acid PDE4 inhibitors led to this series of sulfone analogues. Evaluation of the structure-activity relationship of substitutions on the phthalimide group led to the discovery of an acetylamino analogue 1S, which is currently in clinical trials.
