Integrifolian-1,5-dione and a revised structure for 'africanone', biogenetically related sesquiterpene ketones from Lippia integrifolia
The fusion of the bicyclo[8.1.0]undecane system in the unique sesquiterpene diketone integrifolian-1,5-dione was found to be cis by X-ray analysis. A revised structure was derived for 'africanone' after reconsideration of the mass spectral data. The revised structure is based on a novel se...

Sumario: | The fusion of the bicyclo[8.1.0]undecane system in the unique sesquiterpene diketone integrifolian-1,5-dione was found to be cis by X-ray analysis. A revised structure was derived for 'africanone' after reconsideration of the mass spectral data. The revised structure is based on a novel sesquiterpene skeleton and was confirmed by a biomimetic synthesis from integrifolian-1,5-dione. © 1991. |
