Stereocontrolled Total Synthesis of the Unnatural Enantiomers of Castanospermine and 1-epi-Castanospermine

A concise practical synthesis (13 steps, ca. 10-12percent overall yield) of the unnatural enantiomer of castanospermine ((-)-1) and its 1-epimer 2 from 2,3,4-tri-O-benzyl-D-xylose (3) is described.Key steps in the synthesis are two organometal aldehyde ad
