A full account of the enantioselective totalsynthesis of virgatolide B is reported. Key features of the synthesis include an sp3–sp2 Suzuki–Miyaura cross-coupling of a β-trifluoroboratoamide with an aryl bromide, regioselective intramolecular carboalkoxylation, and a 1,3-anti-selective Mukaiyama aldol reaction. Intramolecular hydrogen bonding governed the regioselectivity of the key spiroketalization
