Crystal structure of 1-isopropyl-4,7-dimethyl-3-nitronaphthalene

Abstract

The title compound, C15H17NO2, was synthesized from a mixture of α-himachalene (2-methylene-6,6,9-trimethylbicyclo[ 5.4.01,7]undec-8-ene) and β-himachalene (2,6,6,9-tetramethylbicyclo[ 5.4.01,7]undeca-1,8-diene), which were isolated from an oil of the Atlas cedar (Cedrus Atlantica). The naphthalene ring system makes dihedral angles of 68.6 (2) and 44.3 (2)°, respectively, with its attached isopropyl C/C/C plane and the nitro group. In the crystal, molecules held together by a C-H⋯O interaction, forming a chain along [101].
