Abstract

Abstract - Methyl 4-deoxy-4-dimethoxyphosphinoyl-2,3-O-isopropylidene-13-D-ribopyranoside (12a) and methyl 2,4-dideoxy-4-dimethoxyphosphinoyl-13-D-etythro-pentopyranoside (20) were efficiently prepared respectively from methyl2,3-O-isopropylidene-[3-D-ribopyranoside (7a) and its 3,4-O-isopropylideneisomer (7b) in appreciably improved total yields compared with those via previously reported routes.Compounds (12a, 20) were led to D-ribofuranos and 2-deoxy-D-ribofuranose phospho sugars (4, 5).
