Pyrimidine 4'-thionucleosides of the formula I STR1 wherein Y is hydroxy or amino, and X is chloro, bromo, iodo, trifluoromethyl, C2-6 alkyl, C2-6 alkenyl, C2-6 haloalkenyl or C2-6 alkynyl and physiologically functional derivatives thereof. These compounds have utility as anti-vital agents.

Treatment of methyl 3,5-di-O-benzyl-2-deoxy-α,β-D-erythro-pentofuranoside with α-toluenethiol and conc. hydrochloric acid gave 3,5-di-O-benzyl-2-deoxy-D-erythro-pentose dibenzyl dithioacetal (21).Mesylation of 21 and ring closure gave benzyl 3,5-di-O-benzyl-2-deoxy-1,4-dithio-α,β-L-threo-pentofuranoside.Inversion of configuration at C-4 of 21 was achieved by the Mitsunobu reaction, to produce 4-O-benzoyl-3,5-di-O-benzyl-2-deoxy-L-threo-pentose dibenzyl dithioacetal.Successive debenzoylation, mesylation, and ring closure then gave the title compound.Several new dithioacetal derivatives of 2-deoxy-D-erythro-pentose were prepared in exploratory routes to the described thio sugar or as intermediates.
