Synthesis of chacotriose analogues

Abstract : We report here the synthesis of three chacotriose analogues, namely β -L-fucopyranosyl-(1→2)-[β-L-fucopyranosyl-(1→4)]-D-glucopyranose, β-L-fucopyranosyl-(1→2)-[β-L-fucopyranosyl-(1→4)]-D-galactopyranose, and α-L-rhamnopyranosyl- (1→2)-[α-L-rhamnopyranosyl-(1→4)]-α-D-galactopyranose.
