## Abstract Reaction of different glycosyl donors with 5‐hydroxy‐__N__‐methyl‐2,3‐diphenylindole (1C) led only to __O__‐glycosylation (compounds 6a–c and 8c‐α,Ξ²). Depending on the __O__‐protection of the glycosyl donors (2a–c, 3b, 4c), the β‐products were obtained mainly or exclusively. The corresp
