An efficient synthesis of enantiomerically-pure β-aryl-γ-lactams is described. The principal feature of this synthesis is the practical resolution of β-aryl-γ-lactams with (S)-Naproxen. The procedure is based on the Michael addition of nitromethane to benzylidenemalonates, which was easily obtained, followed by the reduction of the γ-nitroester in the presence of Raney nickel and the subsequent saponification/decarboxylation reaction. The utility of this methodology was highlighted by the preparation of enantiomerically-pure (R)- and (S)-Baclofen hydrochloride.

[PROBLEMS] To provide a compound which can be used for the treatment of a disease associated with a calcium-sensing receptor (CaSR), particularly hyperparathyroidism. [MEANS FOR SOLVING PROBLEMS] It is found that a novel pyrrolidine derivative having an aminomethyl group substituted by an arylaklyl group or the like or a salt thereof has an excellent CaSR agonistic modulation effect and also has an excellent selectivity in the inhibition of CYP2D6 which may cause a drug-drug interaction. Thus, the novel pyrrolidine derivative is useful as a therapeutic agent for a disease associated with CaSR (e.g., hyperparathyroidism, renal osteodystrophy and hypercalcemia).
