Abstract

The regioselective conversion of selected carbohydrate derivatives into their allylic cyclic acetals was achieved by successive treatment with dibutyltin oxide, acrolein diacetate and catalytic amount of tetrakis(triphenylphosphine)palladium(0). Methods for removal of the new protecting group are discussed.
