An efficient and simple route is presented to the synthesis of some iminothiazolidinone derivatives. ฮฑ-Chloro amide derivatives undergo coupling reaction with isothiocyanate in the presence of a mild base, followed by nucleophilic substitution of chlorine by the sulfur atom of isothiocyanate.
6-Chloro-1H-quinoxalin-2-one-2, 3-14C was prepared by the novel condensation of 4-chloro-1,2-phenylenediamine with glyoxylic acid-I4C (U) . transformed further into 2,6-dichloroquinoxaline-2, 3-14C and 6-chloro-2-(1 '-piperazinyl) -quinoxaline-2,3-I4C.
