摘要

A variety of 1-(o-alkylphenyl)-and 1-(o-o'-dialkylphenyl)-pyrrolidines and-piperidines were prepared by the gas phase alumina mediated condensation of tetrahydrofuran (THF), tetrahydropyran (THP) or the corresponding diols with primary aromatic amines in fair to high yield. This methodology can also be used for the synthesis of 1- phenylhexahydroazepine from aniline. A mechanistic interpretation of the catalytic action ...
