Abstract
Abstract We describe a convenient preparation method of 1, 5-dicarbonyl compounds from enol ethers, methyl vinyl ketone and boron triflouride etherate. In the presence of an alcohol, high or quantitative yields are obtained even with enol ethers of hindered ketones. In contrast without alcohol, yields are considerably lower.
