Xiong, Zhaoming,Li, Yulin,Liao, Renan,Li, Zhengming
, p. 477 - 477 (2007/10/03)
An efficient and diastereoselective synthesis of (-)-10-epi-α-cyperone (1) is described, using the asymmetric Michael addition of the chiral imine, derived from (+)-dihydrocarvone (2), to ethyl vinyl ketone as a key step.
An efficient and stereoselective synthesis of (+)-α-cyperone
Tenius, Beatriz S.M.,Rohde, Adrians R.,Victor, Mauricio M.,Viegas Jr., Claudio
, 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

, p. 2607 - 2612 (2007/10/03)
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.
1,5-DICARBONYL COMPOUNDS A GENERAL PREPARATION METHOD
Duhamel, P.,Hennequin, L.,Poirier, J. M.,Tavel, G.,Vottero, C.
, p. 4777 - 4786 (2007/10/02)
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.
