MK-1084 is a potent KRAS G12 inhibitor characterized by a complex macrocyclic ring system incorporating two atropisomeric axes from a restricted rotation around both C-C and N-C bonds. Herein, we report an efficient synthetic approach to manufacture MK-1084 to enable clinical trials. By leveraging the in-depth understanding of the inherent properties of axial chirality, we discovered and developed a one-pot crystallization-induced diastereomer transformation (CIDT)/carbonylation process to establish the unique and challenging macrocyclic core with double axial chiral centers from a racemic advanced precursor and readily available raw materials.
