The relative configuration of the title compounds has been determined by 'H-NMR measurements at 300 MHz. In contradistinction to prevailing opinion, it was found that 4-OXO derivatives prefer the cis-configuration. While the cis/truns ratio is 82: 18 for the parent 1,2,3,4,4a,9,10, lOa-octahydrophen
