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.
