Stereoselective total synthesis of natural product crisamicin A (1) was accomplished for the first time via the Pd/TMTU-catalyzed alkoxycarbonylative annulation to generate a uniquecis-pyran-fused lactone, an intermolecular Diels−Alder reaction to construct the pyranonaphthoquinone unit, and a novel Pd−thiourea pincer complex-catalyzed homocoupling of functionalized naphthoquinones.
