A single-step synthesis of methyl 3-O-methyl-α-D-manno-, -α-D-galacto-, -α-L-rhamno-, and -α-L-fuco-pyranoside

Mycobaterial polysaccharides and antibiotics often contain some partially methylated monosaccharide units. Thus, 3-O-methylated methyl glycopyranonsides are useful as authentic samples for structure determinations, or as intermediates for the synthesis of some natural products. Several methods have been developed for the synthesis of the 3-methyl ethers of methyl glycopyranosides.

Synthesis of Certain Disaccharides Containing a α- or β-L-Rhamnopyranosidic Group and the Substrate Specificity of α-L-Rhamnosidase from Aspergillus niger

To investigate the substrate specificity of α-L-rhamnosidase from Aspergillus niger, the following seven substrates were synthesized: methyl 3-O-α-L-rhamnopyranosyl-α-D-mannopyranoside (1), methyl 3-O-α-L-rhamnopyranosyl-α-D-xylopyranoside (2), methyl 3-O-α-L-rhamnopyranosyl-α-L-rhamnopyranoside (3), methyl 4-O-α-L-rhamnopyranosyl-α-D-galactopyranoside (4), methyl 4-O-α-L-rhamnopyranosyl-α-L-mannopyranoside (5), methyl 4-O-α-L-rhamnopyranosyl-α-D-xylopyranoside (6), and 6-O-β-L-rhamnopyranosyl-D-mannopyranose (7). Compounds 1 - 6 were well-hydrolyzed by the crude enzyme, but 7 was unaffected.
