compound, via allyl 2,3-di-O-methyl-4-O-(3,6-di-O-methyl-β-D-glucopyranosyl)-α-L-rhamnopyranoside, were also developed. The formylmethyl glycoside was coupled to bovine serum albumin using ‘reductive amination’ in the presence of sodium cyanoborohydride to give a glycoconjugate useful for the serodiagnosis of antibodies to the major glycolipid of Mycobacterium leprae in the sera of leprosy patients. 5′
