Palmerolide A is a recently disclosed marine natural product possessing striking biological properties, including potent and selective activity against the melanoma cancer cell line UACC-62. The total syntheses of five palmerolide A stereoisomers, including the originallyproposed (1) and the revised [ent-(19-epi-20-epi-1)] structures, have been accomplished. The highly convergent and flexible strategy
A formaltotalsynthesis of the 20‐membered marine macrolide, palmerolide A from chiral pool tartaric acid is described. Elaboration of a γ‐hydroxy amide, which is derived from the desymmetrization of tartaric acid amide, and Boord olefination are the pivotal reactions employed for the synthesis of the chiral building blocks, and Stille coupling and ring‐closing metathesis (RCM) are used to assemble

Enantioselectiveformalsynthesis of macrolactone palmerolide A, a polyketide marine natural product, is described. Key strategies in the synthesis include the oxidative furan ring-opening of a chiral furyl carbinol for the installation of the 1,4-dienol core and a Jung nonaldol–aldol reaction for the dienamide core.

Synthetic efforts towards the total synthesis of the revisedstructure of marine macrolide palmerolide C is reported. Synthesis of the triol unit present in the C8,C9, C10 positions was achieved from d-ribose while Johnson orthoester rearrangement and a Wittig reaction were used to construct the C1–C7 component of the macrolactone. The key macrolactone unit was assembled using intermolecular Heck coupling
