摘要

Herein, we report a concise, greener, solvent-free, and novel one pot method for the synthesis of 2-morpholino-3-aryl-5-aroyl thiophenes using 1-morpholino-2-arylethanethione, N, N′-dimethyl formamide dimethyl acetal, and various phenacyl bromides. The driving force for this reaction is the removal of N, N′-dimethylamine from 3-(dimethylamino)-1- morpholino-2-arylprop-2-ene-1-thione resulting in various trisubstituted thiophenes (2- ...
