Abstract
Abstract Methylation of methyl 4,6-O-benzylidene-α- D -mannopyranoside, followed by removal of the benzylidene group, tritylation, tosylation, detritylation, methylation, and removal of the protective tosyl and methyl glycoside groups gave syrupy 2,3,6-tri-O-methyl-D-mannose, characterized by a crystalline di-p-nitrobenzoate. Monotosylation of the 4,6-O-benzylidene derivative gave a 3-O-tosyl derivative; hydrolysis of the benzylidene group, followed by methylation, and removal of the protective tosyl and methyl glycoside groups gave crystalline 2,4,6-tri-O-methyl-α,β- D -mannopyranose, characterized by a crystalline N-phenylglycosylamine.
