Simple modular di- and tripeptides with a primary amine at the N-terminus catalyze the aqueous asymmetric aldol reaction between unmodified ketones and aldehydes to furnish the corresponding β-hydroxy ketones with up to 86% ee in water and 99% ee in aqueos media.
N 末端带有伯胺的简单模块化二肽和三肽可催化未修饰的酮和醛之间的水性不对称羟醛反应,为相应的 β-羟基酮提供在水中高达 86% ee 和在水介质中高达 99% ee 的 β-羟基酮。
