Abstract

An efficient 10-step preparation from 4-methoxypyridine of (2R,3R,4R)-2-acetamido-3,4-dihydroxypiperidine ({''}XyINAe-isofagomine{''}) in optically active form is described. Key steps include an enantioselective reduction with catecholborane/(S)-2-methyl-CBS-oxazaborolidine, and a stereo-selective pseudo-glycosylation of lithium azide by a cyclic sulfite ester. The title compound showed a K-i = 21 mu M when evaluated against the N-acetyl-beta-hexosaminidase from Streptomyces plicatus.
