cis-3-Methyl-1-phenyl-8a,9,10,11,12,12a,12b-hexahydro-1H,3bH-pyrazolo[3,4:2′,3′]pyrano[4′,5′,6′-kl]xanthene

Abstract

The asymmetric unit of the title compound, C23H22N2O2, contains two independent molecules, A and B. The cyclohexane ring of molecule B is disordered, with occupancies for the major and minor conformers of 0.570 (9) and 0.430 (9), respectively. The cyclohexane ring adopts a boat conformation in molecule A and in the major conformer of molecule B, and a chair conformation in the minor conformer of molecule B. In both independent molecules, one of the dihydropyran rings adopts a boat conformation while the other is in a half-chair conformation. The dihedral angle between the pyrazole and phenyl rings is 16.0 (1)° in molecule A and 12.9 (1)° in molecule B. The crystal packing is stabilized by C—H...O and C—H...N intermolecular hydrogen bonds.
