摘要：

Epsilon-Hydroxy (Z)-enol ethers 6 and 12 were readily prepared from D-glucono-1,5-lactone by ring opening, 2-O-alkylation with triflate 3, and Z-specific beta-elimination. Cyclization of 6 and 12 induced by PhSeBF4 or by PhSeOTf provided exclusively beta-connected disaccharides, which were converted into neuraminic acid analogues 10 and 11 or 3-deoxy-2-glycosyl-D-2-hexulofuranosylonate 13, respectively.
