K. Toshima et al., ENVIRONMENTALLY COMPATIBLE C-GLYCOSIDATION OF GLYCALS USING MONTMORILLONITE K-10, Chemical communications, (11), 1996, pp. 1379-1380
The C-glycosidations of glycal acetates 1-4 with allyltrimethylsilane
5, vinyloxytrimethylsilane 6 or isopropenyl acetate 7 using montmorill
onite K-10 as an environmentally acceptable and inexpensive industrial
catalyst under mild conditions proceed effectively to give the corres
ponding 2,3-unsaturated C-glycosides in high yields.
