中文摘要:
从糖类导出的 bifunctional phosphinothioureas 的一个班为在 acrylates 和醛之间的 enantioselective Morita-Baylis-Hillman 反应作为新 organocatalysts 被开发。与基于葡萄糖的 phosphinothiourea 1d 的 10 mol% , allylic 白酒在温和反应条件下面在多达 96% 产量和 83% ee 被获得。
英文摘要:
A class of bifunctional phosphinothioureas derived from saccharide was developed as new organocatalysts for the enantioselective Morita-Baylis-Hillman reaction between acrylates and aldehydes. With 10 mol% of glucose- based phosphinothiourea ld, the allylic alcohols were obtained in up to 96% yield and 83% ee under mild reaction conditions.
