Sio2-pocl2 nano-particles promoted the synthesis of novel structure of alkyl 2-oxo-3,4-diaryloxazolidine-5-carboxylate derivatives

Silica-POCl2 was used as the promoter for the three-component reaction of ethyl/methyl 3-phenyl glycidate, aniline derivatives, and dimethyl carbonate, leads to the synthesis of methyl/ethyl 2-oxo-4-phenyl-3-aryloxazolidine-5-carboxylate derivatives. The desired product was obtained in high yields. © 2021 Bentham Science Publishers

Succinimide-N-sulfonic acid: An efficient and recyclable catalyst for the one-pot synthesis of tetrahydrobenzo[c]acridine-8(7H)-one derivatives

Synthesis of substituted 10,10-dimethyl-7-phenyl-9,10,11,12-tetrahydrobenzo[c]acridin-8(7H)-one derivatives proceeded by the one-pot reaction of aromatic aldehydes, 5,5-dimethylcyclohexane-1,3-dione (dimedone) and 1-naphthylamine, in the presence of Succinimide-N-sulfonic acid (SuSA) has been reported. Simplicity of operation, high yields, easy work-up and a wide range of substrate applicabilities are the key advantages of this methodology. Furthermore, the catalyst can be recovered conveniently and reused efficiently
