S. Jasmin et al., THE SYNTHESIS AND SPONTANEOUS RESOLUTION OF 2-(2-THIOXOTHIAZOLIDIN-3-YL)THIAZOLE, Journal of heterocyclic chemistry, 31(4), 1994, pp. 1079-1081
A single crystalline enantiomer of 2-(2-thioxothiazolidin-3-yl)thiazol
e 5 has been isolated as the major product of the pyrolysis of 3-(2-th
iazolin-2-yl)thiazolidine-2-thione 3 (n = 1); the latter isolated as t
he sole product of the reaction between thiazolidine-2-thione 2 (n = 1
) and diethyl azodicarboxylate (DEAD) in benzene.
