Synthesis of 3-substituted-4-methyl-5-acetyl-4-thiazoline-2-thione
Authors:John J. D'Amico  Frederic G. Bollinger  John J. Freeman
Abstract:The reaction of various potassium salts [RNHC(=S)SK, R = N(CH3)2, morpholino, piperidino, and hexahydro-1-(1H)-azepinyl] with 3-chloro-2,4-pentanedione in ethanol at 25–30° afforded the 1-acetylacetonyl substitutedaminodithiocarbamates 1–4 [RNHC(=S)SCH(COCH3)2]. Under refluxing conditions, the same reactants gave the heterocyclic compounds 5–8. Possible mechanism and supporting ir, nmr and mass spectral data are discussed.
