Abstract
A highly regio- and chemoselective reductive cleavage of benzylidene acetals derived from 1,2- and 1,3-diols was achieved under mild conditions using EtAlCl2-Et3SiH reagent system in good to excellent yields. Labile protecting groups such as N-Boc, N-Cbz and -OTBDMS are found to be stable under the reaction conditions.
