MPEG resins

The same soluble MPEG-resin was used for the immobihzation of (3R,4R)-3,4-bis(diphenylphosphino)-pyrrolidine ligand (56) (Scheme 4.34). The rhodium(I) catalyst was generated in situ from ligand (56) and [Rh(COD)2] BF4 and was found to be active in the asymmetric hydrogenation of prochiral enamides [126]. [Pg.231]

Nonlinear, dendritic or hyperbranched polymers have received considerable attention in recent years. These polymers have seen little use as supports for oligosaccharide synthesis compared to Merrifield or soluble MPEG resins. Nevertheless, some interesting applications of hyperbranched polymers such as hyperbranched polyester and poly(amidoamine) to oligsaccharide synthesis have been reported. [Pg.591]

Glycosylation of MPEG-DOX-OH with 76 was achieved in 95% yield. After deacetylation using DBU in methanol, glycosylation using disaccharide donor 78 was performed and resin-linked trisaccharide was obtained in 85% yield. [Pg.92]
