2-Alkyl(aralkyl)sulfanyl-6-methylpyrimidin-4(3H)-ones and 4-alkyl(aralkyl)oxy-2-alkyl(aralkyl)-sulfanyl-6-methylpyrimidines having similar or different substituents on the sulfur and oxygen atoms were synthesized by alkylation of sodium salts derived from
Halocyclization of substituted 2-(alkenylthio)pyrimidin-6-ones

, p. 660 - 666 (2007/10/03)
Bromination and iodation of 2-(alkenylthio)pyrimidin-6-ones occur selectively and lead to formation of the corresponding 7-oxo-2,3- dihydrothiazolopyrimidinium or 8-oxo-3,4-dihydro-2H-pyrimidothiazinium salts. The selectivity of the reaction is controlled

It has been established that the iodocyclization of 2-allylthio-4(3H)-pyrimidinones occurs at the N(1) nitrogen atom with the formation of 3-iodomethyl-7-oxo-2,3-dihydro-8H-thiazolopyrimidinium iodides and triiodides.

The regioselective S -> N allylic transposition of 2-(allylthio)pyrimidin-4(3H)-ones (3) has been performed by catalysis of Pd(II) salts.Generally the rearrangement gives the N-1 alkylation product predominantly over the N-3-alkylation product.Substituents at the 6-position of 3 reverse the selectivity.Both N-1 and N-3 rearrangement products were transformed to thiazolopyrimidones.
