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