Stepwise oxidative degradation of abietic acid (IV) leads to the stereoisomeric acids (+)‐trans‐[2‐methyl‐2‐carboxy‐cyclohexyl‐(1)]‐acetic acid (XIV) and (‐)‐cis‐[2‐methyl‐2‐carboxy‐cyclohexyl‐(1)]‐acetic acid (XV). Since the dextrorotatory acid XIV had already been obtained from ergosterol D (XVI), this result represents a further proof of the stereochemical identity of C‐10 in the steroids and the cyclic di‐ and triterpenes.
