Advance of Glucosamine and Their Derivatives as Chiral Ligands in Asymmetric Syntheses

氨基葡萄糖是广泛存在于自然界的手性天然产物壳聚糖的降解产物,多手性中心及强的配位能力使之成为制备手性胺基、胺基/膦基配体的理想原料.氨基葡萄糖衍生物作为手性配体参与的不对称反应已成为有机化学中非常活跃的研究领域.综述了氨基葡萄糖衍生物在不对称烯丙基烷基化、Heck反应、1,4-共轭加成反应、烯烃的环氧化反应、烯烃环丙化等反应的最新研究进展.

Glucosamine is a chiral compound degraded from widely existed natural product chitosan. It is becoming an ideal raw material for preparation chiral amine, amine/phosphine ligands due to its more chiral centers and strong coordination abil- ity. The application of glucosamine derivatives as chiral ligands in asymmetric organic reactions has become a very active research area. In this paper, the application of glucosamine derivatives in asymmetric allylic alkylation, Heck reaction, 1,4- conjugate addition reaction, epoxidation reaction of olefins and cyclopropanation of olefin has been reviewed.
