Synthesis of substituted naphtho[1,2-b]benzofuran-7(8H)-ones via photoinduced rearrangement of 4H-chromen-4-one derivatives

A simple and efficient method was developed for the synthesis of substituted naphtho[1,2-b]benzofuran-7(8H)-ones based on the photorearrangement reaction of 4H-chromen-4-one derivatives. The studied reaction includes the photocyclization of the hexatriene system, [1,9]-H-sigmatropic rearrangement and heterocyclic ring opening. The starting terarylenes were prepared via a new three-component tandem condensation of 3-(dimethylamino)-1-(2-hydroxyaryl)prop-2-en-1-ones, arylglyoxals and cyclic 1,3-diketones.

Catalytic asymmetric 1,4-type Friedel-Crafts (hetero)arylations of 1-azadienes: the highly enantioselective syntheses of chiral hetero-triarylmethanes

Direct enantioselective Michael-type Friedel-Crafts arylations and heteroarylations of s-cis 1-azadienes were achieved by applying chiral bifunctional tertiary amine-urea catalysts when using 2-naphthols as the nucleophiles, and phosphoric acid catalysts when using indoles as the nucleophiles. These two catalytic protocols efficiently enabled access to a diverse variety of important benzofuran-containing hetero-triarylmethanes in up to 98% yield and with 99.5 : 0.5 er.

Design, synthesis, and biological evaluation of novel 4H-chromen-4-one derivatives as antituberculosis agents against multidrug-resistant tuberculosis

A series of 4H-chromen-4-one derivatives obtained by scaffold morphing of the benzofuran compound, TAM16, were tested for antitubercular activity. Compound 8d was active against drug-sensitive and multidrug-resistant tuberculosis. A preliminary druggability evaluation showed that compound 8d displayed favorable mouse and human microsomal stability, low cytotoxicity, and acceptable oral bioavailability. An in vivo study indicated that compound 8d exhibited modest efficacy in an acute mouse model of TB after 3 weeks of treatment. Thus, 8d is a promising antituberculosis lead compound.

In our present work, presented an efficient synthesis and anticancer activity evaluation of some novel benzofurancarboxamides. Our proposed approaches provide the possibility to design benzofurans diversity with a considerable chemical novelty. The synthesized substances were selected by the National Cancer Institute (NCI) Developmental Therapeutics Program for the in vitro cell line screening to investigate their anticancer activity. The compounds with significant levels of anticancer activities have been found that can be used for further optimization.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 87-41-2, in my other articles.

Gephysulfuromycin (1) featured a rare single S-bridged 3,12a-epithiotetraphene skeleton. Homophenanthroviridone (2) was found to be cytotoxic to SF-268, MCF-7, and HepG2 cell lines with IC50 values of 5.4 +/- 0.4, 6.8 +/- 0.3, and 1.4 +/- 0.1 mu M, respectively.
