Concise and stereocontrolled syntheses of (+)-1-deoxynojirimycin and (2R,5R)-dihydroxymethyl-(3R,4R)-dihydroxypyrrolidine [(+)-DMDP] were achieved via a diastereomerically enriched oxazine intermediate. The key strategies include the use of 1,3-oxazine as a chiral building block and diastereoselective nucleophilic addition to an aldehyde. Starting from readily available (R)-methyl 2-benzamido-3-((tert-butyldimethylsilyl)oxy)propanoate, (+)-1-deoxynojirimycin was synthesized in 11 steps and 26.2% overall yield while (+)-DMDP was synthesized in 11 steps and 27.1% overall yield, respectively.

Highly diastereoselective nucleophilic additions to cyclic nitrones derived from L-malic acid and D-arabinose have been used for the construction of enantiomerically pure polyhydroxylated pyrrolidines. The synthetic strategy adopted was based on an oxidat
