Efficient total syntheses of (1R, 2R, 3R, 9R, 9aR)-1,2,3,9-tetrahydroxyquinolizidine and its enantiomer

Concise syntheses of two enantiomeric tetrahydroxyquinolizidines, 10 and ent-10 have been achieved from D-arabinose and L-arabinose, respectively. Highly diastereoselective homologation of imine 5 (or ent-5) using 2-(trimethylsiloxy)furan provided the nine-carbon butenolide 6 (or ent-6) which was elaborated into the quinolizidine 10 (or ent-10) via a clean sequence involving, as key operations, DBU-promoted γ-lactone to δ-lactam ring expansion (e.g. 7 to 8) and cyclodehydration of a fully-deprotected hydroxypiperidine employing Ph3, CCl4, Et3N (e.g. 9 to 10). The procedure comprises five steps from 5 or ent-5 and provides the title quinolizidine 10 or its enantiomer ent-10 in 36-37% overall yields.

Versatile β-Lactam Synthons: Enantiospecific Synthesis of (-)-Polyoxamic Acid

An optically pure cis-α-hydroxy β-lactam of predictable absolute configuration prepared from readily available D-mannitol has been utilized for the synthesis of the non-natural enantiomer of polyoxamic acid through a series of stereospecific reactions.

Cycloaddition Reactions of Carbohydrate Derivatives. Part III. A New Route to Swainsonine Analogs.

Swainsonine analogs 10 and 12 have been synthesized from D- and L-arabinose, respectively, using cyclocondensation of azomethines with Danisthefsky's diene followed by stereoselective carbonyl and double bond reduction of the resulting pyridones, chain sh
