Abstract

An approach to stereoselective synthesis of α- or β-3-C-glycosylated l- or d-1,2-glucals starting from the corresponding α- or β-glycopyranosylethanals is described. The key step of the approach is the stereoselective cycloaddition of chiral vinyl ethers derived from both enantiomers of mandelic acid. The preparation of 1,5-anhydro-4,6-di-O-benzyl-2,3-dideoxy-3-C-[(2,3,4,6-tetra-O-benzyl-β-d-glucopyranosyl)methyl]-l-arabino-hex-1-enitol, 1,5-anhydro-4,6-di-O-benzyl-2,3-dideoxy-3-C-[(2,3,4,6-tetra-O-benzyl-β-d-glucopyranosyl)methyl]-d-arabino-hex-1-enitol, and 1,5-anhydro-4,6-di-O-benzyl-2,3-dideoxy-3-C-[(2,3,4-tri-O-benzyl-α-l-fucopyranosyl)methyl]-d-arabino-hex-1-enitol serves as an example of this approach.
