Abstract The asymmetric synthesis of the enantiomerically pure bipiperidine core fragment of a potent dual NK 1 /NK 2 antagonist is described. The utilization of a diastereoselective Michael addition employing Evans’ auxiliary as the key step allowed for the preparation of the fragment on a multi-kilogram scale.
