SYNTHESIS OF HETEROCYCLES VIA ENAMINES-X. REACTIONS OF 1-SUBSTITUTED-4,4,6-TRIMETHYL-1,4-DIHYDROPYRIMIDINE-2(3H)THIONE DERIVATIVES WITH α-HALOGENATED CARBOXYLIC ACIDS AND KETONES

2,4-dioxathiazolidine derivatives(7) have been obtained in synthetically useful yields by the condensations of easily available 1-substituted-4,4,6-trimethyl-1,4-dihydropyrimidine-2(3H) thione derivatives (4) and α-halogenated carboxylic acids in aqueous
