The total syntheses of penmacric acid and its three stereoisomers were accomplished through the intermolecular radical addition reaction of the 4-pyrrolidyl radical derived from trans-4-hydroxy-l-proline. Furthermore, 1′,3-diepi-penmacric acid was synthesized stereoselectively via double stereoinduction in the radical reaction.
