Sg. Mills et al., 1,2,3-TRISUBSTITUTED CYCLOHEXYL SUBSTANCE-P ANTAGONISTS - SIGNIFICANCE OF THE RING NITROGEN IN PIPERIDINE-BASED NK-1 RECEPTOR ANTAGONISTS, Bioorganic & medicinal chemistry letters, 5(13), 1995, pp. 1345-1350
A stereocontrolled synthesis of 1-benzyloxy-2-phenylcyclohexane deriva
tives containing polar substituents at C3 is described. These compound
s, designed to test the role of the ring nitrogen in a related series
of potent piperidine-based substance P antagonists, show similar NK-1
receptor affinity, indicating that the nitrogen may serve a largely st
ructural role in N-substituted piperidine antagonists.
