Reaction of p-trifluoroacetamidophenyl2,4-di-O-benzyl-a-r>-mannopyranoside with 2-0-acetyl-3,4,6-tri-O-benzyl-cy-D-mannopyranosyl chloride gave a trisaccharide derivative which was 0-deacetylated and then treated with ethyl 2,3,4tri-O-benzyl-6-O-dibenzyloxyphosphoryl-l-thio-a-D-mannopyIanoside. The
Syntheses of the octyl and tetradecyl glycosides of 3,6-di-O-α-d-mannopyranosyl-α-d-mannopyranose and of 3,4-di-O-α-d-mannopyranosyl-α-d-mannopyranose. A new way for 2,4-di-O-protection of mannopyranosides

4,6-Di-O-acetyl-2,3-dideoxy-D-erythro-hex-2-enopyranose (4,6-di-o-acetyl-D-pseudoglucal), prepared from 3,4,6-tri-O-acetyl-1,5-anhydro-2-deoxy-D-arubinohex-1-enitol (tri-0-acetyl-D-glucal), was condensed, by catalysis with boron trifluoride, with an equivalent of the original glycal, to give crystal
All of the monodeoxy analogues of methyl 3,6-di-O-alpha-D-mannopyranosyl-alpha-D-mannopyranoside have been synthesized together with two dideoxy (2,3'- and 4,3'-) analogues. The 2'- and 2"-deoxy functions were introduced by NIS-promoted couplings with 2,3,4-tri-O-acetyl-D-glucal as donor, followed b
The crystal structure of a-D-Manp-(1 +3)-/?-D-Manp-( 1-+4)-a-D-GlcNAcp has been determined by the direct method using the multi-solution, tangentzformula, and "magic integer" procedures. The space group is P2,, and 2 molecules are in the unit cell with c1 = 9.894 ( 5), b = 10.372 (6), c = 11.816 (6)
