Synthesis of (2R,3S)-1,2,3-Butanetriol Derivatives From (R)-2,3-O-Isopropylideneglyceraldehyde and of the (2S,3R)-Enantiomers FromD-Glucose. Application to the Synthesis of Enantiomerically Pure Muscarine
Both enantiomers of the O-protected epoxy alcohol derivative 1b have been prepared from (R)-2,3-O-isopropylideneglyceraldehyde and D-glucose, respectively, and utilized in a practical synthesis of L- and D-muscarine iodide and chloride.
