Gold(I)-Catalyzed Glycosylation with Glycosyl ortho-Alkynylbenzoates as Donors: General Scope and Application in the Synthesis of a Cyclic Triterpene Saponin. — The new method can also be used for successful glycosylation of amides, α-selective glycosylation of 2-deoxy sugars, and β-selective sialylation. Moreover, this reaction is one of the key steps in the synthesis of a complex triterpene tetrasaccharide saponin. — (LI, Y.; YANG, X.; LIU, Y.; ZHU, C.; YANG, Y.; YU*, B.; Chem. Eur.
