: A powerful new promoter combination in the aryl C-glycosidation of a diverse range of sugar acetates and aromatic substrates
摘要:
SnCl4/AgOTfa was shown to be a powerful combination for promoting aryl C-glycosidation between various sugar acetates and aromatic substrates. This promoter activates otherwise unreactive peracetylated glycosides, leaving them susceptible to reaction with low electron-donating aromatics. A survey of the reaction application is described.
