The first total synthesis of the benzannulated spiroketal virgatolide A is presented. Key features include sp(3)-sp(2) Suzuki coupling of an enantiomerically enriched beta-trifluoroboratoamide and an aryl bromide, regioselective intramolecular carboalkoxylation, and a 1,3-anti-selective Mukaiyama aldol reaction followed by global deprotection/cyclization with regioselectivity governed by internal hydrogen bonding.
