Takano, Seiichi,Akiyama, Masashi,Sato, Seiji,Ogasawara, Kunio

, p. 1593 - 1596 (1983)

Benzylidene acetals of 1,2- and 1,3-glycols are easily cleft by diisobutylaluminum hydride in a toluene solution at 0 deg C - room temperature to give the corresponding monobenzyl ethers of the glycols.In general the reaction proceeds excellently in regioselective manner depending on the stereochemical environment.
