摘要

综合摘要本研究开发了一种高度立体选择性的镍催化交叉亲电偶联方法，可将容易获得的、新型的、稳定的氧基糖基自由基前体，特别是 1,2-糖基原酯偶联起来。这种方法为合成多种 C-乙烯基糖苷提供了有效途径，其特点是产率高、立体选择性好、反应条件温和、底物范围广以及所得产物可进行多种转化。

Stereoselective Synthesis of C-Vinyl Glycosides via Nickel-Catalyzed Cross-Electrophile Couplings of 1,2-Glycosyl Orthoesters and Vinyl Halides

A highly stereoselective nickel-catalyzed cross-electrophile coupling of readily accessible, novel, stable oxygen-based glycosyl radical precursors, specifically 1,2-glycosyl orthoesters, is developed. This approach offers an effective pathway to synthesize diverse C-vinyl glycosides, characterized by good yields, excellent stereoselectivity, mild reaction conditions, a broad substrate scope, and versatile transformations of the resulting products.
