, p. 197 - 203 (2007/10/03)
An efficient and stereoselective three step synthesis of (+)-α-cyperone 1 is described. The key step involves a stereoselective Michael addition of chiral imine to (R)-dihydrocarvone.
An efficient asymmetric route to eudesmane acids. Total synthesis of (+)-12-hydroxy-α-cyperone, (+)-12-oxo-α-cyperone and (+)-3-oxoeudesma-4,11(13)-dien-12-oic acid

An efficient asymmetric synthesis of (+)-3-oxoeudesma-4,11(13)-dien-12-oic acid 4, (+)-12-hydroxy-α-cyperone 6 and (+)-12-oxo-α-cyperone 7 from (+)-dihydrocarvone 5 is described, which involves a novel diastereoselective preparation of (+)-α-cyperone 8.

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.
