Total synthesis of penmacric acids via an intermolecular radical addition reaction
摘要:
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. (C) 2013 Elsevier Ltd. All rights reserved.
