Provided is a compound which is useful as a therapeutic agent for chronic renal insufficiency and a therapeutic agent for diabetic nephropathy.
The present inventors have made extensive studies on an ornithine derivative having an antagonistic action against an EP4 receptor, and as a result, they have found that by introducing cycloalkanediyl at a C terminal of the ornithine part of the compound of the present invention, the physicochemical properties such as solubility, and the like can be improved, thereby giving further preferred properties as a pharmaceutical. Therefore, they have completed the present invention.
The compound of the present invention exhibits a good antagonistic action against an EP4 receptor, and thus, it is useful as a therapeutic agent for chronic renal insufficiency and diabetic nephropathy.

acetylation of different (±)-cis-N-(alkoxycarbonyl)cyclopentane-1,2-diamines. Depending on the alkoxycarbonyl group, a simple kineticresolution (Boc-derivative) or an interesting dynamic kineticresolution (DKR with Cbz-, Alloc, and ethoxycarbonyl derivatives) has been developed. Racemization for the DKR occurred due to the N,N′ intramolecular migration of the alkoxycarbonyl group.

The disclosure describes a process for the preparation of cyclic optically active amino alcohols of formula (I) by reacting an optically active hydroxycarboxylate of formula (IV) with hydrazine to form an optically active hydroxycarboxylic hydrazide compound of formula (III), then conducting a Curtius reaction in the presence of an alcohol to give an optically active alkoxycarbonylamino alcohol of formula (II), followed by deprotecting the amino group to form the amino alcohol of formula (I).
The variables A1, A2, R1-R6, m, n and * are as defined in the claims.
