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.
