Abstract

Conjugated enaminothioamides react in high-yield with acetylenedicarboxylic acid or its ester derivatives to give 2-enaminathiazolin-4-ones. A similar reaction is observed with propiolic acid and derivatives, giving 2-enamino-1,3-thiazin-4-ones. A substituted thiazoline is quantitatively obtained from propargyl bromide.
