An efficient and stereoselective synthesis of D-iminolyxitol, a potent alpha-galactosidase inhibitor, is achieved in 11 steps over 45% overall yield from N-Boc-O-Bn-D-serine. The key step involves the OsO4-catalyzed syn-selective dihydroxylation reaction of the acyclic gamma-amino-alpha,beta-unsaturated (Z)-ester controlled by an N-diphenylmethylene group.
