2,4-Bis(2-methoxyphenyl)-3-azabicyclo[3.3.1]nonan-9-one

Abstract

In the title compound, C22H25NO3, the molecule has a pseudo-mirror plane. The structure is a positional isomer of 2,4-bis(4-methoxyphenyl)-3-azabicyclo[3.3.1]nonan-9-one [Cox, McCabe, Milne & Sim (1985). J. Chem. Soc. Chem. Commun. pp. 626–628]. The 3-azabicyclo[3.3.1]nonan-9-one moiety adopts a double chair conformation with equatorial orientations of both 2-methoxyphenyl substituents on either side of the secondary amino group. The benzene rings are oriented at an angle of 33.86 (4)° with respect to each other and the methoxy groups point towards the carbonyl group. The crystal structure is stabilized by intermolecular N—H...π interactions.
