The first synthesis of a ‘C-disaccharide’
Abstract
Condensation of 2,3,4,6-tetrabenzylglucopyranolactone with the anion of methyl 6,7-dideoxy-2,3,4-tri-O-benzyl-α-D-gluco-hept-6-ynopyranoside followed by triethylsilane reduction provided, after hydrogenolysis, the first example of a synthetic β(1 → 6′)-‘C-disaccharide.’
