We describe a convenient preparation method of 1,5-dicarbonyl compounds from enol ethers, methyl vinyl ketone and boron trifluoride etherate.In the presebce of an alcohol, high or quantitative yields are obtained even with enol ethers of hindered ketones.

In this report, a general method for the preparation of 1,5-dicarbonyl compounds and six membered ring annelation is described.This method involves the reaction of hemiacetal vinylogs 1 with enol ethers 2 or 3 in the presence of a Lewis acid.This reaction was successfully applied to the enol ethers of α and α,α'-hindered ketones such as 2,2,6-trimethyl cyclohexanone. α-Cyperone and 6-epi-α-cyperone were obtained using this process.
