ved aryl C-glycosides were synthesized in good to excellent yields by the coupling of structurally diverse terminal sugar alkynes, aroyl chlorides and 1, 2-phenylenediamine. The protocol is general, mild and efficient. It was suitable for various terminal sugar alkynes and aroyl chlorides, with 37 selected examples. The sugar substrates include pyranosides, furanosides, and acyclic sugars with sensitive
摘要 通过结构多样的末端糖炔烃、芳酰氯和 1, 2-苯二胺的偶联,以良好至优异的产率合成了新型 3 H -1,5-苯二氮卓衍生的芳基C-糖苷。该协议是通用的、温和的和有效的。适用于各种末端糖炔烃和芳酰氯,有37个例子。糖底物包括吡喃糖苷、呋喃糖苷和具有敏感和庞大保护基团的无环糖。芳酰氯含有给电子、吸电子和电子中性的取代基。
