Abstract: (6S)-Methyl-L-swainsonine, C₉H₁₇NO₃, together with the 6R-epimer, was formed in a synthetic sequence in which there was an ambiguity in configuration at position C-6. This ambiguity was resolved by establishing the relative stereochemistry of the title compound by X-ray crystallographic analysis. The absolute configuration was determined by the use of D-glycero-D-gulo-heptono-1,4-lactone as the starting material.
