Abstract

The title compound C20H24O4 crystallizes in the orthorhombic space group P21212, with a = 10.245(3), b = 17.103(3), c = 9.879(3) Å, D c = 1.260 g cm −3, and Z = 4. Nepetanudone is postulated to be formed by a [4+4] cycloaddition of two 5,9-dehydronepetalactone moieties to give an asymmetric dimer in which each pair of atoms is magnetically nonequivalent. The compound was recovered from extracts of Nepeta nuda ssp. albiflora.
