Synthesis of Substituted Piperidines from <i>N</i>,<i>N</i>-Bis[(benzotriazol-1-yl)methyl]amines

Abstract

N,N-Bis[(benzotriazol-1-yl)methyl]benzylamines and N,N-bis[(benzotriazol-1-yl)methyl](p-N',N'-dimethylphenyl)amine on reaction with allyltrimethylsilanes yielded substituted piperidines. Other N,N-bis[(benzotriazol-1-yl)methyl]anilines (unsubstituted and p-CH(3), OCH(3), Cl) gave julolidines (2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij] quinoline).
