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.

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.
