Isosteric N-arylpiperazine replacements in a series of dihydropyridine NPY1 receptor antagonists

Bioorg Med Chem Lett. 2004 Dec 20;14(24):5975-8. doi: 10.1016/j.bmcl.2004.10.005.

Abstract

4-Amino-N-arylpiperidines serve as effective bioisosteres for N-arylpiperazines in the series of dihydropyridine NPY1 receptor antagonists. These were prepared by a ZnCl2-mediated reductive amination reaction between elaborated primary amines, 2 or 5, and 4-arylpiperidones.
