A microwave-assisted synthesis of 2-(4-((1-phenyl-1H-1,2,3-triazol-4-yl)methoxy)phenyl)-1H-benzo[d]imidazoles from a phenylazide, propargyloxybenzaldehyde and a 1,2-diaminobenzene is proposed.

The supramolecular polymerization of pyrene imidazoles 1 and 2, governed by H-bonding and C-H···π interactions, yields aggregates showing the characteristic bluish emission pattern of pyrene-based monomers.

Sulfur substituted 3-vinylpyrrole 10 was prepared from 3-thio-acetylpyrrole 9 by alkylation with alkyl halide in the presence of propylene oxide. Functionalized 4-alkylthioindoles were made by Diels-Alder reaction of the 3-vinylpyrrole 10 with dienophiles. Chuangxinmycin analogues were synthesized by using some of the functionalized 4-alkylthioindoles as key intermediates.

Starting from commercially available amines and propargylamides a variety of substituted imidazoles were synthesized via a novel hydroamination-cyclization sequence. The target compounds are obtained in good to excellent yields in the presence of catalytic amounts of zinc triflate.

Hexagonal mesoporous silica (SBA-15) was prepared and then functionalized by(3-mercaptopropyl)trimethoxysilane. The obtained 3-mercaptopropyl functionalized SBA-15 (SBA-Pr-SH) was then oxidized using H2O2 in methanol under an acidic condition to give sulfonic acid functionalized mesoporous silica (SBA-Pr-SO3H). Th...

Using molecular simplification and hybridization approaches, a series of 2-(benzylthio)-1H-benzo[d]imidazoles was synthesized evaluated as in vitro inhibitors Mycobacterium tuberculosis (M. tuberculosis) growth. Compounds 6p 6z were considered the lead compounds from this molecules, with minimal inhibitory concentration (MIC) values 6.9 3.8 μM against M. H37Rv, respectively. Additionally, leadi...

An efficient, simple, and green four-component reaction for synthesizing 1,2,4,5-tetrasubstituted imidazoles is developed. In present work exploring the use of Samarium triflate as a heterogeneous catalyst aldehydes, aromatic amines, benzil, ammonium acetate. The current approach offers many advantages, such excellent yields, shortening time, reusability catalyst, mild conditions.
