Rapid Formation of Dibutylstannylene Acetals from Polyhydroxylated Compounds under Microwave Heating. Application to the Regioselective Protection of Polyols and to a Catalytic Tin-mediated Benzoylation

Abstract
The formation of dibutylstannylene acetals from polyols and dibutyltin oxide is accelerated under microwave heating. The method is applied to the regioselective benzoylation of a variety of polyols. Some preliminary results on a catalytic tin-mediated benzoylation of polyols are also presented.
