SYNTHESIS AND POLYCONDENSATION OF GALACTO-CONFIGURATED MONOMERS VIA THE TRITYL-CYANO-ETHYLIDENE-PROCEDURE

4-O-Acetyl-1,2--3-O-trityl-α-D-fucopyranose (13) and methyl 4-O-acetyl-1,2-O--3-O-trityl-α-D-galactopyranuronate (14) were synthesised.Trityl-cyanoethylidene condensation of the monomer 14 gave protected β-D-GalpA-(1->3)-D-GalpA-oligosaccharide derivatives with high stereoselectivity and a degree of polymerisation (d.p.) of eight.In the case of the D-fucose monomer 13, the yield of oligomers is surprisingly low and the d.p. does not exceed seven.This result is in contrast to the d.p. 20 - 60 obtained with other 6-deoxy-sugars, as previously described by Kochetkov and coworkers.
