natural product itself. The preparation of a complete set of DE ring system isomers bearing the unnatural stereochemistry at the labile C8, C11, and C14 sites was accomplished for comparison and established that C8 is prone to epimerization to the more stable, unnatural S versus R absolute stereochemistry if it bears an ester, but not a carboxamide, substituent. Additionally, an improved synthesis of the
