The first total synthesis of (-)-3-oxoeudesma-1,4,11(13)-trien-7αH-12-oic acid has been described. The key step is one-pot reaction involving dehydrogenation and allylic oxidation with selenium dioxide.

The chiral keto alcohol 6a was prepared from (S)-(+)-carvone.Because two steps in this process gave only modest yields of isolated materials, an alternative route was developed.Racemic keto alcohol 6b was prepared from enedione rac-13a by a more efficient process.

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.
