Abstract

In the cycloaddition reactions of a biperifunctional compound, 1,3,6-triphenylimidazo[1,2-c]thia^IVzole, to a variety of unsymmetrically substituted olefinic dipolarophiles, one of the two peripheral thiocarbonyl ylides has exclusively contributed affording good yields of the regioselective [3 + 2] cycloadducts.
