Inhibitors of the cytochrome P450 enzyme aromatase, which is involved in the biosynthesis of estrogens from androgens, are of proven utility in the treatment of hormone-dependent breast cancer. The determination of the crystal structure of one such inhibitor, 3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (2) and its 3-butyl analogue (3) is described. In the absence of three-dimensional structural information

Analysis of the proton NMRspectra of 3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (rogletimide, 1) shows that it exists in solution with the aromatic ring in an axial position; the same conformation was found for aminoglutethimide. Excess lithium diisopropylamide treatment of 1 formed a dianion which methylated at C-5. The major product with the methyl group trans to the pyridyl ring retained this ring
