Abstract

Abstract Reverse nucleoside derivatives of 2-(methylsulfanyl) uracils 6a-d were prepared by treating of the sodium salt of 2-(methylsulfanyl) uracils (5a-d) with methyl 2, 3-O- isopropylidene-5-Op-toluenesulfonyl-β-D-ribofuranoside (2). The alkylation of 2-thiouracils 4a-d with methyl 5-deoxy-5-iodo-2, 3-O-isopropylidene-D-ribofuranoside (3) afforded the corresponding S-ribofuranoside derivatives 8a-d. Deisopropylidenation of 6a-d and 8a-d ...
