Practical and highly stereoselective aryl and allyl C-glycosidation methods using unprotected sugars as glycosyl donors have been developed. Aryl C-glycosidations of several unprotected 2-deoxy sugars with phenol and naphthol derivatives by the combined u

Highly regio- and stereo-selective C-arylglycosylations of the protected free sugars 1-4, the unprotected methyl glycosides 6-9 and the unprotected free sugars 10 and 11 with 2-naphthol 5 are effectively realized by the combined use of TMSOTf-AgClO4 (TMSO
Efficient C-arylglycosylation of 1-O-methyl sugar by novel use of TMSOTf-AgClO4 catalyst system

Highly β-stereoselective C-arylglycosylations of the 1-O-methyl sugars 1-4 with 2-naphthol (9) were effectively achieved by novel combinational use of a catalytic amount of TMSOTf-AgClO4 as an activator. Also, C-arylglycosylations of the 1-O-ac
Improvement in O -> C Glycoside Rearrangement Approach to C-Aryl Glycosides: Use of 1-O-Acetyl Sugar as Stable but Efficient Glycosyl Donor

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.
