4,4-Dinitro-5,6,7,8,9,10-hexahydro-4H-cyclonona[d]isoxazole

Abstract

The title compound, C10H13N3O5, was designed as a potential endothelin receptor antagonist and as a probe of the structural requirements of the endothelin receptor binding site. The isoxazole ring is planar and the cyclo­nona­ne moiety lies approximately in the plane of the heterocycle. The mol­ecules are packed in the crystal structure by ionic and van der Waals inter­actions.
