Omega-(Methoxycarbonyl)alkyl glycopyranosides of D-mannose having C4, C-7, C-9, C-12, and C-15 carbon chains, L-fucose and 2-acetamido-2-deoxy-D-mannose having C-7 and C-9 carbon chains. D-xylose and 2-acetamido-2-deoxy-L-fucose having a C-9 carbon chian, and 9-(methoxycarbonyl)-3,6-dioxanoyl glycopyranosides of D-mannose. 2-acetamido-2-deoxy-D-mannose, and L-fucose were' synthesized as intermediates for coupling to human serum albumin in order to examine the effect of chain length and hydrophobicity of the spacer arm on the binding specificity of lectins. 8-(Methoxycarbonyl)octyl glycosides of beta-D-Man-(1 --> 2)-alpha-D-Man, alpha-D-Man-(1 --> 2)-alpha-D-Man, alpha-D-ManNAc-(1 --> 2)-alpha-D-Man, beta-D-GlcNAc-(1 --> 2)-alpha-D-Man, and their 6-O-positional isomers, beta-D-Man-(1 --> 6)-alpha-D-Man, alpha-D-Man-(1 --> 6)-alpha-D-Man, alpha-D-ManNAc-(1 --> 6)-alpha-D-Man, and beta-D-GlcNAc-(1 --> 6)-alpha-D-Man, were also synthesized.
