A new enantioselective synthesis of pinellic acid, a trihydroxy unsaturated fatty acid exhibiting oral adjuvant activity for nasally administered influenza vaccine, has been accomplished using a cross-metathesis reaction between two terminal olefin intermediates as the key step. This synthesis is the shortest to date, furnishing pinellic acid in 17% overall yield via only seven steps from a readily available known dihydroxy ester. (C) 2009 Elsevier Ltd. All rights reserved.

A stereocontrolled total synthesis of six lipoxin B isomers are described. The flexible and stereoselective strategy involves Sharpless asymmetic epoxidation and pinylborane asymmetic reduction to secure the three hydroxyl-bearing stereocenters and a Wittig-type as well as palladium(0)-copper(I) coupling reactions to construct the carbon skeleton of the target molecules.
