This work describes stereoselective preparation of β-C-aryl/vinyl glucosides via mild Ni-catalyzed reductive arylation and vinylation of C1-glucosyl halides with aryl and vinyl halides. A broad range of aryl halides and vinyl halides were employed to yield C-aryl/vinyl glucosides in 42%–93% yields. Good to excellent β-selectivities were obtained for C-glucosides by using tridentate ligand.

镍催化的葡萄糖基卤化物与芳基/乙烯基卤化物的镍还原还原偶联，可实现β选择性制备 C-芳基/乙烯基葡糖苷

这项工作描述了通过温和的Ni催化的还原性芳基化和C 1-葡萄糖基卤化物与芳基和乙烯基卤化物的乙烯基化，立体选择性地制备β- C-芳基/乙烯基葡糖苷。广泛使用的芳基卤化物和乙烯基卤化物可产生C-芳基/乙烯基葡糖苷，产率为42％–93％。通过使用三齿配体，对C-葡糖苷获得了良好至优异的β-选择性。
