N-Morpholino-δ8-dihydro-abietamide

Abstract

The title compound, C24H39NO2 (systematic name: 4-{[1,4a-dimethyl-7-(propan-2-yl)-1,2,3,4,4a,5,6,7,8,9,10,10a-dodeca- hydro-phenanthren-1-yl]carbon-yl}morpholine), has been synthesized from 8-dihydro-abietic acid. Two cyclo-hexene rings adopt half-chair conformations, whereas the cyclo-hexane and morpholine rings are each in the chair conformation. Two methyl groups are in an axial position with respect to the tricyclic hydro-phenanthrene nuclei.
