Abstract

... Pieroh discovered in 1939 that acetals react with enol ethers in the presence of a Lewis acid to give 3-a1koxyacetals.l This reaction, which was later suggested to proceed via carbocationic intermediates,2 has become an important method in organic synthe~is ... J. Org ... Chem., Vol. ...
