Oxyfunctionalization of abundant carboxylic acids represents a direct approach to synthesizing α-hydroxy acids, which are valuable intermediates of various active pharmaceutical ingredients. Although ideal, the transformation is yet to be accomplished. Herein, enantiocomplementary C(sp3)–H oxyfunctionalization for the synthesis of α-hydroxy acids was realized by a cooperative strategy of substrate
丰富的羧酸的氧官能化代表了合成α-羟基酸的直接方法,α-羟基酸是各种活性药物成分的有价值的中间体。尽管理想,但转变尚未完成。在此,通过α-酮戊二酸依赖性非血红素芳氧基链烷酸铁双加氧酶的底物工程、同源物筛选和蛋白质工程的合作策略,实现了用于合成α-羟基酸的对映互补C( sp 3 )–H氧官能化。该反应为三种67种α-羟基酸提供了简洁的合成路线,具有高效率和选择性(产率高达90%,ee高达>99%)。这些独特的互补反应丰富了生物催化氧官能化反应的种类。
