Abstract
A systematically varied series of conformationally restricted ketones, readily prepared from N-acetyl-D-glucosamine, were tested against representative olefins as asymmetric epoxidation catalysts showing useful selectivities against terminal olefins and, in particular, typically difficult 2,2-disubstituted terminal olefins.
摘要
从 N-乙酰-D-葡萄糖胺出发，经过系统变化的一系列构象限制酮，可以很容易地制备出来，然后将它们作为不对称环氧化催化剂来测试，对代表性烯烃具有有用的选择性，特别是通常难以反应的 2,2-二取代末端烯烃。
