Efficient Synthesis and Antimicrobial Evaluation of Pyrazolopyranopyrimidines in the Presence of SBA-Pr-SO3H as a Nanoporous Acid Catalyst
A simple, efficient, and environmentally friendly method has been developed for the synthesis of a series of tricyclic fused pyrazolopyranopyrimidines via a one-pot three-component reaction of barbituric acids, aromatic aldehydes, and 3-methyl-5-pyrazolone in the presence of SBA-Pr-SO3H. SBA-15 mesoporous silica material functionalized with propyl sulfonic acid groups was used as a heterogeneou...

متن کاملSynthesis of 1,2-Disubstituted Benzimidazoles in the Presence of SBA-Pr-SO3H as a Nano Solid Acid Catalyst
In this article, simple, convenient synthesis of 2-aryl-1- arylmethyl-1H-1,3-benzimidazole (1,2-disubstituted benzimidazoles) via condensation of 1,2-phenylenediamine and aromatic aldehydes using SBA-Pr-SO3H as a nanoporous solid acid catalyst in green protocol was reported.
متن کاملGreen Synthesis of Pyrazol‑chromeno[2,3‑d]pyrimidinones Using SBA-Pr-SO3H as an Efficient Nanocatalyst
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...
