Abstract

A variety of 2,3-epoxy acetals have been found to undergo regioselective reductions with zinc-chlorotrimethylsilane and lithium aluminium hydride to give 2-hydroxy and 3-hydroxy acetals respectively. Their oxidation followed by hydrolysis furnished the corresponding 1,2- and 1,3-diones in good yields.
