Various 1,6-dithiaspiro heterocycles can be synthesized from 1,3-thiazole-5(4H)-thiones via 1,3-dipolar cycloadditions, Diels-Alder reactions, ring expansion of oxiranes, and C-alkenylation followed by radical cyclization. 1,3-Thiazole-5(4H)-thiones with

Benzonitrile ylides, imines, and oxides undergo smooth 1,3-dipolar cycloaddition reactions with the exocyclic C,S-double bond of 4,4-dimethyl-2-phenyl-2-thiazolin-5-thione (1), yielding heterocyclic spiro-compounds.The structure of the cycloadducts 5c, 5c
