✦ Synopsis
Treatment of 2,3:4,5-di-g-isopropylidene-k-arabinose diphenyl dithioacetal (la) with sodium methylsulfinyl carbanion in DMSO has previously been shown2 to produce ga via extraction of the acidic C-l hydrogen and concomitant elimination of acetone. Workup of the reaction with water gave 2-deoxy-4,5-Q-isopropylidene-RS ,/SR
