Some hydroxy-steroids were transformed into the corresponding chloro-steroids with Walden inversion, when treated with sulfuryl chloride in pyridine ; testosterone (I), 4-chlorotestosterone (IV), 17β-hydroxy-5α-androstan-3-one (V), 5α-androstane-3β, 17β-diol 3-acetate (VIII), and estradiol 3-benzoate (IX) were introduced to the corresponding 17α-chloro compounds, II, III, VI, VIIa, and X, respectively. From androsterone (XI) and isoandrosterone (XIV) were obtained 3β-chloro-5α-androstan-17-one (XII) and 3α-chloro-5α-androstan-17-one (XIII) respectively.
当用吡啶中的磺酰氯处理时,一些羟基类固醇通过Walden反转转化为相应的氯代类固醇;睾酮(I)、4-氯睾酮(IV)、17β-羟基-5α-雄甾烷-3-酮(V)、5α-雄甾烷-3β, 17β-二醇-3-乙酸酯(VIII)和雌二醇-3-苯甲酸酯(IX)分别被引入对应的17α-氯代化合物,即II、III、VI、VIIa和X。由雄甾酮(XI)和异雄甾酮(XIV)分别获得了3β-氯-5α-雄甾烷-17-酮(XII)和3α-氯-5α-雄甾烷-17-酮(XIII)。
