We report for the first time that the imidate radical can be efficiently added to glycals to generate glycosyl radicals, based on which a general, toxic-reagent-free synthesis of C-glycosides of 2-deoxy-2-amino sugars has been developed. Complementary to previous strategies, the reaction is 1,2-trans-stereoselective and could use aryl alkenes as substrates. The late-stage functionalization and density
我们首次报道了可以将
亚胺酯自由基有效地添加到糖基中以生成糖基自由基,基于此,已经开发了 2-
脱氧-2-
氨基糖的C-糖苷的通用、无毒试剂合成。作为对先前策略的补充,该反应具有 1,2-反式立体选择性,并且可以使用芳基
烯烃作为底物。报告了后期功能化和密度泛函理论计算。
