Electrophile-induced Cyclization of γ,δ-Alkenylimines as a Synthetic Route to Pyrrolidines and Piperidines
Kimpe, Norbert de,Boelens, Mark,Piqueur, Johan,Baele, Jan
, p. 1925 - 1928 (1994)
Cyclization of γ,δ-alkenylimines with bromine in dichloromethane gave instantaneous formation of cyclic iminium bromides, which were converted into either pyrrolidines of piperidines, depending upon the substitution pattern.This reaction has been applied
PREPARATION OF PIPERIDINES FROM δ-CHLOROIMINES
Sulmon, Paul,Kimpe, Norbert de,Schamp, Niceas
, p. 3907 - 3922 (2007/10/02)
The reaction of δ-chloro imines with various nucleophiles e.g. metal hydrides, potassium cyanide, alcohols and alkoxides gave rise to piperidines, 2-cyanopiperidines and 2-alkoxypiperidines respectively.These piperidines were formed by the addition of the
