The solid-phase synthesis of glycopeptides was first realized by applying the polymeric benzyl ester principle of Merrifield. According to this methodology, Lavielle and associates (50) used 7V-(tm-butyloxycarbonyl)-<9-glycosyl serine derivative 153 for condensation with resin-linked alanine 154. [Pg.299]

Despite the reduced nucleophilicity of iV-acylated serine derivatives, direct glycosylation of Fmoc protected serine and threonine esters is feasible, and has become a popular approach to 0-linked glycopeptides (Scheme 5.5).19 In this approach, the pentafluorophenyl (Pfp) ester has a... [Pg.162]

The glycosylating disaccharide derivative (30) was of limited value when used with the diserine compound (3D. A better method for making the disubstituted dipeptide involved condensation of two disaccharide serine derivatives. Two deoxy derivatives of... [Pg.23]

Several amino-sugar glycosides have been prepared using glycosyl halides. The azido-derlvative (30) has been bonded to serine and serine derivatives to produce glycopeptlde haptens with T specl-ficlty and, in related work, to a Schiff-base protected... [Pg.24]
