Effective synthesis of n-aryl-substituted 1,5,3-dithiazepinanes and 1,5,3-dithiazocinanes

摘要

Selective methods were developed for the synthesis of N-aryl-1,5,3- dithiazepinanes and N-aryl-1,5,3-dithiazocinanes by transamination of N-tert-butyl-1,5,3-dithiazepinane or recyclization of 1-oxa-3,6- dithiacycloheptane and 1-oxa-3,7-dithiacyclooctane by the action of aniline derivatives in the presence of Sm(NO_3)_3·6H _2O catalyst.
