Synthesis of polyhydroxylated indolizidines and piperidines from Garner's aldehyde: Total synthesis of (-)-swainsonine, (+)-1,2-di-epi-swainsonine, (+)-8,8a-di-epi-castanospermine, pentahydroxy indolizidines, (-)-1-deoxynojirimycin, (-)-1-deoxy-altro-nojirimycin, and related diversity

Diastereoselective and diverse synthesis of polyhydroxylated indolizidines and piperidines have been described, where a common chiral intermediate 2-(hydroxymethyl) piperidine-3-ol is converted into (-)-swainsonine, (+)-1,2-di-epi-swainsonine, (+)-8,8a-di-epi-castanospermine, pentahydroxy indolizidines, (-)-1-deoxynojirimycin, (-)-1-deoxy-altro-nojirimycin, and related diversity. The key steps were hydroxy directed intramolecular aminomercuration, Mitsunobu cyclization, and diastereoselective dihydroxylation.

Stereoselective formal total synthesis of (-)-swainsonine from Garner's aldehyde

A simple and facile stereoselective formal total synthesis of (-)-swainsonine has been reported starting from Garner's l-serine derived oxazolidine aldehyde. Our synthetic strategy involves stereoselective allylation and Still olefination as key intermedi

General approach to glycosidase inhibitors. Enantioselective synthesis of deoxymannojirimycin and swainsonine

(Chemical Equation Presented) Deoxymannojirimycin (2) and swainsonine (4) have been synthesized from each enantiomer of the same bicyclic carbarnate precursor 7. The key intermediate was prepared by a simple and efficient three-step synthesis involving RCM of the diene 8, which in turn is easily accessible in any configuration from enantiomerically enriched 2,3-epoxy-4-penten-1-ol 9.
