A series of trans,trans-1-phenyl-3-pyrrol-1-ylindan-2-carboxamide derivatives has been synthesized in eight steps starting from cinnamic acid or 3,3-diphenylpropionic acid. The trans,trans configuration of these carboxamides has been established by X-ray analysis and by NOE experiments in NMR. These new compounds were evaluated for their potential NK-1, NK-2 and NK-3 receptors binding affinity. The N,N-disubstituted carboxamides bound selectively on NK-2 receptors.
