A new general methodology for the asymmetric synthesis of polyhydroxypiperidines is described. The readily available achiral olefin 4 was transformed to 5-des(hydroxymethyl)-1-deoxynojirimycin (1) and its mannose analog 10 via regioselective aminohydroxylation (AA), ring-closing metathesis (RCM), and diastereoselective dihydroxylation reactions. Thus, the developed methodology made it possible to install
描述了一种不对称合成多羟基哌啶的新通用方法。容易获得的非手性烯烃4通过区域选择性氨基羟基化(AA),闭环易位(RCM)和非对映选择性二羟基化反应被转化为5-去(羟甲基)-1-脱氧野oji霉素(1)及其甘露糖类似物10。因此,开发的方法使以高度立体声控制的方式在1和10中安装所有立体声中心成为可能。
