Herein, we disclose an approach for the asymmetric synthesis of both enantiomers of an anti-inflammatory furanone. The approach is based on the utilization of a Morita-Baylis-Hillman adduct as starting material and has as key step a selective epoxide-opening/benzylic oxidation mediated by Palladium (II). This sequence afforded an advanced intermediate, which was used to accomplish the total synthesis. Experimental evidences allowed us to suggest a mechanistic proposal for the oxidation Palladium(II)-mediated.

The COX-2 inhibitor DFP [5,5-dimethyl-3-(2-propoxy)-4-methanesulfonylphenyl)-2(5H)-furanone] was found to have a long half-life in humans. Analogues have been characterized in order to optimize pharmacokinetics. This has lead to the discovery of 5(S)-(5-ethyl-5-methyl-3-(2-propoxy)-4-methanesulfonylphenyl)-2(5H)-furanone analogue 11 a potent and selective COX-2 inhibitor which is metabolized to a greater extent than DFP upon incubation with rat and human hepatocytes, suggesting a shorter half-life in humans.
