摘要
Substituted 1,2,3,4-tetrahydroquinolines and related condensed nitrogen-heterocycles are formed highly regio- and diastereo-selectively with yields ranging from 57 to 100% by intermolecular polar [4 pi(+) + 2 pi] cycloadditions of cationic 2-azabutadienes from thiomethylamines and various dienophiles.
