5-sulfosalicylic acid as an efficient organocatalyst for environmentally benign synthesis of 2-substituted benzimidazoles
A water soluble, Bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. Cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally fri...

متن کاملFacile and Rapid Synthesis of 3,4-Dihydropyrimidin-2(1H)-one Derivatives Using [Et3NH][HSO4] as Environmentally Benign and Green Catalyst
5-acetyl-6-methyl-4-aryl-3,4-dihydropyrimidin-2(1H)-ones were synthesized in good to excellent by one-pot three-component Biginelli condensation in the presence of ammonium salt [Et3NH][HSO4] as an inexpensive and green catalyst under solvent-free conditions. High yields, short reaction time, easy work-up, a green environment which requires no toxic o...

متن کاملAn Efficient and Environmentally Benign Chemical Synthesis of Testolactone
Testolactone was obtained commercially by microbial transformation of either testosterone or progesterone and also synthetically, albeit in low yield. The only chemical synthesis of 1 so far described in the literature starting from dehydroepiandrosterone (2) is shown in Scheme 1. The strategy followed in this synthetic approach consisted in the initial formation of the lactone ring by a Baeyer...
