Acid instead of base: Kinetic resolution of secondary alcohols is realized using chiral Brønsted acid catalyzed acylation instead of the conventional basic conditions. A broad range of functional groups are tolerated, such as aldehydes, carboxylic acids, and enoates. The selectivity factor (s) reaches up to 215 at ambient temperature.
酸代替碱:使用手性布朗斯台德酸催化的酰化反应代替常规的碱性条件,可实现仲醇的动力学拆分。可以容忍各种各样的官能团,例如醛,羧酸和烯酸酯。在环境温度下,选择性因子(s)高达215。
