Abstract

Vinylsilanes are rapidly becoming important terminators for cationic cyclizations. 2 We have described2" Sb a general stereocontrolled synthesis of alkylidene azacyclics by the intramolecular reaction of vinylsilanes with iminium ions (1-2). During the course of these studies, we became interested in whether these weakly reactive cyclization components would also participate in
