Syntheses are described of 2-azido-4,6-di-O-benzyl-2,3-dideoxy-d-ribo-hexopyranosyl fluoride, 6-O-acetyl-2-azido-3-O-benzyl-2,4-dideoxy-d-xylo-hexopyranosyl fluoride and 2-azido-3,4-di-O-benzyl-2,6-dideoxy-d-glucopyranosyl fluoride. These glycosyl donors were coupled with the acceptor 1d-2,3,4,5-tetra-O-benzyl-1-O-(4-methoxybenzyl)-myo-inositol and the alpha-coupled products were transformed into alpha-d-3dGlcpN-PI
