Abstract
1,2-Dideoxy-3,4:5,7-bis-O-(1-methylethylidene)-D-gluco- and D-galacto-hept-l-ynitols were synthesized starting respectively from benzyl α,β-D-glucopyranoside and from benzyl α,β-D-galactopyranoside by bis-acetonidation, hydrogenolysis, Wittig reaction with chloromethylenetriphenylphosphorane, and dehydrohalogenation. The structures of the obtained compounds were confirmed by the NMR spectrocopic data which also allowed to determine the conformations of the molecules.
