A facile, efficient, and highly diastereo‐ and enantioselective bromoetherification of diolefinic diols has been developed using an amino‐thiocarbamate catalyst. Further manipulations of the bromoether products enabled entry into a new class of spirocycles which are distinctively lacking in the literature.
使用氨基硫代氨基甲酸酯催化剂已开发出一种简便,高效且高度非对映和对映选择性的二烯烃二醇溴醚化方法。溴醚产物的进一步处理使得能够进入文献中明显缺乏的新型螺环。
