Abstract
Regioselective acetal-bond cleavage of 4,6-O-benzylidene-and 4,6-O-(4-methoxybenzylidene)-α-d-altropyranosides by DIBAL or Li(C2H5)3BH–TiCl4 is described. The sense of regioselectivity could be controlled by suitable choice of the protecting group of hydroxyl function at C-3. Reduction of 4,6-O-alkylideneglucopyranosides by DIBAL is also examined.This publication has 9 references indexed in Scilit:
