Formation of N–S Bonds in Reactions of 2-[2-Oxo-1-(tosyloxyimino)-2-phenylethyl]pyrimidin-4(3H)-one and Its 6-derivatives with Thiourea and Potassium Thiocyanate
摘要:
Reaction of potassium thiocyanate with 2-[2-oxo-1-(1-tosyloxyimino)-2-phenylethyl]pyrimidin-4-(3H)-one derivatives led to the formation of a new fused heterocyclic system with a common nitrogen atom, substituted 7H-[1,2,5]thiadiazolo[2,3-a]pyrimidin-7-one.

The synthesis of 2-(2-amino-4-arylthiazol-5-yl)pyrimidin-4(3H)-ones from the available 2-(2-oxo-2-arylethylidene)-2,3-dihydropyrimidin-4(1H)-ones was developed.
