Circular dichroism of some steroidal α-ketols and their acetates
Abstract An examination of the CD spectra of certain steroidal α-ketols and their acetates revealed instances where the Cotton effect of the ketone n → π * transition does not obey the octant rule. This was discussed in terms of the conformational preferences of the α-substituents. The relevance of these results to earlier configurational assignments on A-ring α-ketols in the cucurbitacin series was assessed.
