The Efficient, Enantioselective Synthesis of Aza Sugars from Amino Acids. 1. The Polyhydroxylated Pyrrolidines.
Beginning with (+)-serine or (-)-serine, as appropriate, convenient, high-yield, enantioselective synthesis of all eight stereoisomeric 2-hydroxymethyl-3,4-dihydroxypyrrolidines (the enantiomeric pairs of iminoribitol, -arabinitol, -xylitol, and -lyxitol) can be effected. The absolute configuration of the starting amino acid defines the set of azasugars produced.
