A set of Pd‐catalyzed ortho‐directed C—H glycosylation reactions with glycosyl chloride donors using various N‐linked bidentate auxiliaries has been developed for synthesis of C‐aryl glycosides. A broad range of pyranose and furanose moieties can be installed on the ortho position of arylamine, carbazole, indole and benzylamine type substrates in high yield and with high regio‐ and diastereoselectivity
已经开发了一组使用各种N-连接的双齿状助剂的Pd催化的邻位C-H糖基化反应与糖基氯供体的反应,用于合成C-芳基糖苷。可以在芳胺,咔唑,吲哚和苄胺类底物的邻位上以高收率,高区域选择性和非对映选择性的方式安装各种吡喃糖和呋喃糖部分。这些助剂可以在相对温和的条件下轻松安装和拆卸。
