Divergent Synthesis of Bioactive Marine Meroterpenoids by Palladium-Catalyzed Tandem Carbene Migratory Insertion

The divergent synthesis of (+)-8-epi-puupehedione, (+)-chromazonarol, (+)-yahazunol, and (+)-yahazunone has been accomplished. The key steps were a palladium-catalyzed tandem carbene migratory insertion of an aryl iodide and a drimanal hydrazone, a highly regioselective enol reduction, an oxa-Stork–Danheiser transposition reaction, an electrocyclization of a conjugated tetraenone, and a redox reaction of dimethoxybenzenes.
