A stereoselective synthesis of the proposed structure of palmerolide C (1), a cytotoxic marinemacrolide isolated from the Antarctic tunicate Synoicum adareanum, utilizes a convergent carbonyl‐based couplingstrategy to construct the C1–C24 carbon skeleton (see scheme). Compound 1 was shown to be a diastereomer of palmerolide C, and the structural revision of the natural product is proposed.
