The stereoselective cyclixation of an a-cyanoamine containing a vinyl group induced by Tic4 in a methylene chloride solution, produces cis 2,6-dialkylpiperidine; whereas a similar reaction of an acyanoamine containing a silyl substituted vinyl group gave the corresponding tram isomer only. The pipe
