| Abstract: | The unambiguous syntheses of methyl 3,4,6-tri-O-methyl-α-d-mannopyranoside (6) and methyl 3,4-di-O-methyl-α-d-mannopyranoside (10) were performed by routes involving methyl 3-O-benzoyl-4,6-O-benzylidene-α-d-mannopyranoside (1) to form methyl 2-O-p-tolylsulfonyl-d-mannopyranoside (4). Compound 4 directly led to 6, and, via a 6-trityl derivative, to 10. |
