Abstract
BH3/Bu2OTf is an effective reagent to reductively cleave 4,6-O-benzyli dene acetals of various hexopyranosides to the corresponding 4-O-benzy l ethers. 4,6-O-Isopropylidene acetals can be similarly cleaved. Commo n protecting group'S are stable to the reaction conditions. (C) 1997 E lsevier Science Ltd. All rights reserved.
