[摘要]:A novel method of the enantioselective synthesis of 2-substituted hexahydroquinolin-4-ones is described. The method relies on a Pd-catalyzed asymmetric allylic amination using a chiral diaminophosphine oxide (DIAPHOX) preligand and diastereoselective intramolecular Mannich reaction. The developed synthetic method could be applied to the catalytic asymmetric synthesis of (+)-2-epi-cis-195A. |
