artificial catalysts. Current strategies to rival enzymatic catalysis require unmodified or minimally modified structures of active sites, gigantic molecular weight, and sometimes the use of harsh conditions such as extremely low temperatures in organic solvents. Herein, we describe a design of small molecules that act as the simplest metalloenzyme‐like catalysts that can function in water, without mimicking
与人工催化剂相比,酶具有压倒性的优越催化作用。目前与酶催化竞争的策略要求活性位点的结构未经修饰或修饰程度最低,分子量巨大,有时还需要使用苛刻的条件,例如在有机溶剂中的极低温度。本文中,我们描述了一种小分子的设计,该分子充当最简单的类似于金属酶的催化剂,可以在水中起作用,而不会模拟酶的结构。这些人造催化剂使用甲醛水溶液有效地促进了对映选择性直接型羟醛反应。反应遵循迈克尔斯-门腾动力学,并且在水中构建了耐热不对称环境。
