We describe herein an efficient method for the preparation of a functionalised bicyclic framework (6-substituted 7-bromo-aza-bicyclo[2.2.1]heptane) through the selective opening of the aziridium 2 with organocuprates in up to 90% yield. These interesting chiral building blocks were then utilised as novel ligands in the rearrangement of epoxides to afford chiral allylic alcohols.
我们在本文中描述了通过选择性打开叠氮基2与有机铜酸盐以高达90%的产率制备官能化双环骨架(6-取代的7-溴-氮杂-双环[2.2.1]庚烷)的有效方法。然后将这些有趣的手性结构单元用作环氧化物重排中的新型配体,以提供手性烯丙基醇。
