Combine the protected monosaccharide acceptor with the glycosyl donor in the presence of an appropriate promoter or catalyst. Common promoters include Lewis acids like trimethylsilyl triflate (TMSOTf) or Lewis bases like tris(pentafluorophenyl)borane. The reaction should be carefully controlled to form the desired glycosidic bond.
