Enantioselective synthesis of a marine antibiotic (−)-atrop–abyssomicinC was accomplished in 21 steps, in 1.8% overall yield (4%, based on the recovered starting material). The key steps of the synthesis are the formation of the functionalized cyclohexane core by an organocatalyzed Tsuji–Trost reaction, the formation of a tricyclic spirotetronate unit by a gold-catalyzed reaction sequence and the
