enzymes. Herein, C-aryl glycosylation was established for the synthesis of 2-sulfur C-aryl glycals and 1,2-dihydrobenzofuran-fused C-aryl glycosides via interrupted Pummerer process, featured with sulfonium-tethered [3,3]-sigmatropic rearrangement between sulfoxide glycals and phenols. This protocol offers a broad substrate scope with diverse glycosyl and phenols. Dapagliflozin, Empagliflozin, and Ipragliflozin
C-芳基糖苷由于其独特的抗酶水解特性,是药物发现中重要的碳水化合物衍生物。在此,建立了通过间断Pummerer法合成2-硫C-芳基糖醛和1,2-二氢苯并呋喃稠合C-芳基糖苷的C-芳基糖基化,其特征在于锍系链的[3,3 ] -σ重排亚砜糖醛和酚类。该实验方案提供了具有多种糖基和酚类的广泛底物范围。达格列净、恩格列净和伊格列净类似物分别是直接实现的。
