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(NO3)(3)center dot 6H(2)O catalyst.

A new method was developed for preparation of N-(1,5,3-dithiazepan-5-yl)- and N-(1,5,3-dithiazocan-5-yl)amides by transamination of N-tert-butyl-1,5,3-dithiazepane and N-tert-butyl-1,5,3-dithiazocane, and also by recyclization of 1-oxa-3,6-dithiacycloheptane and 1-oxa-3,7-dithiacyclooctane with carboxylic acids hydrazides in the presence of catalysts based on rare earth elements.
