| Abstract/Summary |
Methyl 3,5-di-O-benzoyl-α-L-arabinofuranoside, prepared by a five-step synthesis from Larabinose, was condensed with 2,3,4-tri-O-acetyl-α-D-xylopyranosyl bromide under modified Koenigs—Knorr conditions using mercuric cyanide as a catalyst and acid scavenger in dichloromethane, giving a high yield (77 %) of the O-protected disaccharide VIII. Removal of acyl groups afforded the desired model compound – methyl 2-O-β-D-xylopyranosyl-α-L-arabinofuranoside. 1H and 13C NMR spectra of the synthesized compounds are also presented.
