摘要：

Allyl C-glycosidations of the totally unprotected glycals, L-rhamnal (1), D-glucal (2), D-galactal (3) and D-fucal (4), with allyltrimethylsilane (5) using TMSOTf proceeded much more effectively than those of the corresponding acetylated glycals 10 similar to 13 to furnish the unprotected and 2,3-unsaturated allyl alpha-C-glycosides 6 similar to 9 in high yields, respectively.
