C-Glycosides are stereoselectively formed by the titan-(IV)-catalysed addition of silyl enolethers 2 to 2,4,6-tri-O-acyl-1-deoxy-D-erythro-hex-1-enopyran-3-uloses 1 followed by elimination of the 4-acyloxy substituent.Cyclohexenyl silylether 2a reacts wit
STEREOSELECTIVE SYNTHESIS OF C-GLYCOSYL COMPOUNDS via MICHAEL ADDITION OF TRIMETHYLSILYL ENOL ETHERS AND ENAMINES TO HEX-1-ENOPYRAN-3-ULOSES

The titanium(IV)-catalyzed addition of trimethylsilyl enol ethers to 2,4,6-tri-O-acylhex-1-enopyran-3-uloses (3 and 4) gave stereoselectively 3,6-di-O-acyl-4-deoxy-β-D-glycero-hex-3-enopyranosyl-2-ulose derivatives.The formation of the C-glycosyl bond was
