1-Isopropyl-4,7-dimethyl-2,8-dinitro-naphthalene.


ABSTRACT: The title compound, C(15)H(16)N(2)O(4), was synthesized from a mixture of ?-himachalene (2-methyl-ene-6,6,9-trimethyl-bicyclo-[5.4.O(1,7)]undec-8-ene) and ?-himachalene (2,6,6,9-tetra-methyl-bicyclo-[5.4.0(1,7)]undeca-1,8-diene) which were isolated from an oil of the Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol-ecules. In each of the two mol-ecules, two O atoms of one nitro group are disordered over two sets of sites with site-occupancy factors of 0.636?(5):0.364?(5) and 0.832?(5):0.168?(5). The crystal structure features weak C-H?O hydrogen bonds.

The title compound, C(15)H(16)N(2)O(4), was synthesized from a mixture of α-himachalene (2-methyl-ene-6,6,9-trimethyl-bicyclo-[5.4.O(1,7)]undec-8-ene) and β-himachalene (2,6,6,9-tetra-methyl-bicyclo-[5.4.0(1,7)]undeca-1,8-diene) which were isolated from an oil of the Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol-ecules.
