title: Total synthesis of the microtubule-stabilizing agent (-)-laulimalide.
abstract: [structure: see text] The total synthesis of the potent microtubule-stabilizing anticancer agent (-)-laulimalide has been achieved in 27 steps and 2.9% overall yield. Notable features are the use of Jacobsen HDA chemistry for the enantioselective construction of the side chain dihydropyran, a diastereoselective aldol coupling using chiral boron enolate methodology, a Mitsunobu macrolactonization, and a Sharpless AE to introduce the epoxide onto des-epoxy-laulimalide.
