The synthesis of the marine natural products, siphonarienal, siphonarienone, and pectinatone is described employing desymmetrization strategy to create three consecutive stereogenic centers. The key intermediate 7 was made by asymmetric hydroboration of the known meso-olefin using (−)-IPC2BH followed by PCC and Baeyer-Villiger oxidation reactions.

The marine natural product (+)-pectinatone containing ‘skip’ 1,3-dimethyl stereocentres was synthesised via the iterative alkylation of propanal SAMP-hydrazone with β-branched iodides. Factors affecting the selectivity of the alkylation reaction and the in situ formation of volatile β-branched iodides are described.
