Leveraging on the exquisitely turning on or switching off the directing effect of the C3-OH located o-diphenylphosphanylbenzoyl (o-DPPB) group in glycals, a reagent-controlled protocol for divergent and regio- and stereo-selective synthesis of C-glycosides has been established. In particularly, the silence of the directing effect of o-DPPB was achieved by the introduction of ZnCl2 additive, which is operationally simple and efficient. The flexibility of the novel protocol was exhibited not only… Expand
