Abstract

The palladium (II)-catalyzed carbonylation of various enol esters in the presence of methanol under pressurized carbon monoxide was investigated. As typical results, the carbonylation of isopropenyl acetate afforded a cyclocarbonylation product, 2-methoxy-2, 5, 5-trimethyl-1, 3-dioxolan-4-one, in 46% yield under carbon monoxide of 150 atm at 100° C, whereas vinyl acetate selectively gave an α-hydroesterification product, methyl 2- ...
