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).

to julolidines with two different substituents on C-1 and C-7. Reaction of 1-[(benzotriazol-1-yl)methyl]-1,2,3,4-tetrahydroquinoline (25) with enolizable aldehydes gives a mixture of tetrahydroquinolines 26-29 which are converted into single julolidine products upon treatment with sodium hydride, LAH, or phenylmagnesiumbromide. Reactions of 1,2,3,4-tetrahydroquinolines with benzotriazole and 2 molar
