chloride (2) afforded 2-[[(2,2-Dimethyl-1,3-dioxolan-4-yl) methyl]thio]pyrimidin-4(1H)-ones 3a-c and 4-[[(2,2-Dimethyl-1,3-dioxolan-4-yl)methyl]thio] pyrimidin-2(1H)-ones 8a,b, respectively. Further alkylation with 2 and/or 2,3-O-isopropylidine-1-O-(4-toluenesulfonyl)-glycerol (4) gave the acyclo N-nucleosides 5a-c and 9a,b whose deprotection afforded 6a-c and 10a,b. 2-(Methylthio)pyrimidin-4(1H)-ones 11a-c
