P-glycoprotein inhibitors. Considerable attention has been paid to the synthesis of biologically active jatrophanes although very few have succumbed to total synthesis. Herein we report a synthesis of the cyclopentane core of pepluanin A, a potent P-glycoprotein inhibitor, that features an iodocarbocyclization and an invertive acetal formation as key steps.
