摘要
Based on an umpolung strategy, a series of novel full substituted, optically active dihydrothiophenes, which contain several functional groups, such as amine, ester and oxime groups, were obtained via an efficient organocatalytic asymmetric a formal thio[3+2]-cyclization of acyclic thioamides with (E)alpha-nitrostyrenes.
