title: Synthetic investigation toward apigenin 5-O-glycoside camellianin B as well as the chemical structure revision.
abstract: Capitalizing on the Au(i)-catalyzed ortho-alkynylbenzoate glycosylation method, the first total synthesis of the proposed structure of apigenin-5-O-glycoside camellianin B was achieved, wherein three approaches, one linear and two convergent, were established, through which the synthetic structures were firmly corroborated. Meanwhile, through the synthesis of anthentic camellianin B via commercially available camellianin A, the misassigned structures of camellianins A and B were revised.
