| 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. |
