Compounds having the structure (or their salts):
are used to treat or reduce the likelihood of acquiring androgen-dependent diseases, such as prostate cancer, benign prostatic hyperplasia, polycystic ovarian syndrome, acne, hirsutism, seborrhea, androgenic alopecia and male baldness. The compounds can be formulated together with pharmaceutically acceptable diluents or carriers or otherwise made into any pharmaceutical dosage form. Combinations with other active pharmaceutical agents are also disclosed.

unexpected synthesis of previously unknown 4-amino-5-methylsulfonyl-2,3-dihydroisothiazole 1,1-dioxides (also called β-amino-α-mesyl-γ-sultams). Thus, the reaction of mesyl chloride with hindered α-aminonitriles is accompanied by the formation of interim N-(1-cyanoalkyl)(methylsulfonyl)methanesulfonamides which, in turn, undergo the сarbanion-mediated sulfonate (sulfonamido) intramolecular cyclization

of a complex study involving physical methods (NMR and IR spectroscopy, X-ray diffraction study) and DFT calculations (performed at PBE0 QZVP level of theory) allowed us to rationalize and formulate the rules of structure‒activity relationship for the discussed sultams. It turned out, that the simplest way to predict the reactivity of α-functionalized β-enamino γ-sultams is the 1H NMR spectroscopy:
