1-O-Acetyl sugars serve as efficient glycosyl donor in the O -> C-glycoside rearrangement approach to C-aryl glycosides.Model study was carried out on three types of 2-deoxy-glycosyl acetates including amino sugar derivative.Comparison of the promoters, Cp2HfCl2-AgClO4, SnCl4, BF3*OEt2 is described.

Regio- and stereo-controlled formation of C-aryl β-D-olivoside linkage is achieved by the reaction of naphthol or anthrol derivatives with D-olivosyl fluoride.The reaction is efficiently promoted by Cp2HfCl2-AgClO4 and the bond formation occurs selectivit

The reduction of enulose 1a predominantly leads to L-digitoxal (3a), although this method presents a sluggish reaction with moderate yields.In contrast, the preparation from L-digitoxose (4a) in a three-step one-pot procedure represents an advantageous approach.Regioselective 3- or 4-O-alkylations are achieved by phase-transfer catalysis method or via stannylidene intermediates to give monosaccharide precursors of the L-ribo series valuable for further interglycosidic linking.
