Abstract

Cis and trans‐methyl‐4‐deoxy‐2, 3‐O‐isopropylidene‐6‐O‐methyl‐4‐methylthio‐methylene‐α‐D‐lyxo‐hexopyra‐nosides are prepared by a Wittig reaction. Methods are described for the determination of the configuration of the geometrical isomers whose Raney‐Nickel reduction leads to derivatives of 4‐deoxy‐4‐methyl‐hexoses of the D‐manno and D‐talo series.

## Abstract Two novel methods for the synthesis of terminal acetylenic sugars, both involving a chain extension by one carbon unit, are described. In the first procedure, an aldehydo‐sugar is treated with dibromomethylenetriphenyl‐phosphorane, then with __n__‐butyllithium and finally with water. Th
