该中间体在本合成路线中的序号：(XII)In a related way, canrenone (I) was converted to mexrenone (XI) by an analogous sequence including cyanide addition to give enamine (IX), hydrolysis to diketone (X), and ring opening with NaOMe. The microbiological oxidation of mexrenone (XI) yielded either the 9-a (XII) or the 11-b (XIII) hydroxylated compounds, which were dehydrated to the olefin (VIII), whose epoxidation, as before, afforded eplerenone.
