    Abstract: The present invention refers to a process for the industrial-scale preparation of 17β-hydroxy- 6β,7β;15β,16β-dimethylene-3-oxo-17α-pregn-4-ene-21-carboxylic acid y-lactone, known by the common name of Drospirenone, in the form of a fine powder without the use of mechanical grinding or micronization techniques, but rather exploiting a double change of crystalline form, from Crystalline Form I to Crystalline Form II and from Crystalline Form II to Crystalline Form I. The invention also refers to the new Crystalline Form II of Drospirenone obtained in the process.

    Abstract: The present invention relates to a novel process for the synthesis of abiraterone and in particular abiraterone acetate, a compound of formula (I) reported below: having pharmacological activity suitable for slowing down the progression of advanced stage prostate cancer. The process is characaterised by the fact that the intermediate triflation step is carried out on prasterone (DHEA) or its 3-acetate using Ar-N(OTf) 2 as the triflation reagent, but where Ar is not phenyl, and by the fact that the base used in this step is an alkali metal alcoholate.

    Abstract translation: 本发明涉及一种用于合成阿维酮酮，特别是阿维昔龙醋酸酯的新方法，该方法报告如下：具有适于减缓晚期前列腺癌进展的药理学活性。 该方法的特征在于以下事实：中间三价充气步骤使用Ar-N（OTf）2作为三氟化试剂进行prasterone（DHEA）或其3-乙酸酯，但是Ar不是苯基，而事实上 该步骤中使用的碱是碱金属醇化物。
