The first and catalyticenantioselective total synthesis of hypocrolide A (>99% ee) in 12 steps, as well as other botryanes, is described. The absolute configurations of these compounds have been unambiguously confirmed or reassigned accordingly. The key reactions in this study include an unusual rhodium-catalyzed intramolecular [4 + 2] cycloaddition and a biomimetic oxidative [3 + 2] cycloaddition
