-
, (2008/06/13)
The invention provides a process for the preparation of cyclic ketones of the general formula STR1 in which R represents an optionally substituted alkyl or cycloalkyl group and R 1 and R 2 independently represent an optionally substituted alkyl, cycloalkyl or aryl group, which comprises heating a compound of the general formula STR2 in which X represents a chlorine or bromine atom and R is as defined above, with a compound of the general formula STR3 in which R 1 and R 2 are as defined above, in the presence of an organic acid.Certain cyclic ketones of formula (I) are useful as intermediates in the preparation of certain fungicidally active cyclopentane derivatives.

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.
