Fig. 2: Profile of approaches to glycosyl phosphosaccharides and our method.
From: Stereoselective gold(I)-catalyzed approach to the synthesis of complex α-glycosyl phosphosaccharides

In red are the α-configuration of the formed glycosidic bond and the benzyl (Bn) group. In yellow is the gold(I) catalysis. In pink is the indication of the role of gold(I). In blue are the features of the present approach.
