The asymmetric synthesis of (3R)-N-methyl-2-oxo-[1,4′-bipiperidine]-3-acetamide in quantity
摘要:
The asymmetric synthesis of the enantiomerically pure bipiperidine core fragment of a potent dual NK1/NK2 antagonist is described. The utilization of a diastereoselective Michael addition employing Evens' auxiliary as the key step allowed for the preparation of the fragment on a multi-kilogram scale.
