    摘要: The disclosure concerns 5.beta.-hydroxy-.DELTA..sup.6 -steroids of the general formula ##STR1## wherein R.sup.1 is hydrogen, acyl, lower alkyl, or the tetrahydropyranyl residue andR.sup.2, R.sup.3 individually are respectively hydrogen or jointly are methylene andX stands for oxygen, the groupings ##STR2## (wherein R.sup.4 means hydrogen or acyl) and ##STR3## (wherein R.sup.5 means hydrogen or lower alkyl) and a process for the preparation thereof by reacting corresponding 7.alpha.-chloro-5.beta.,6.beta.-epoxy steroids in an inert solvent with metallic zinc in a lower aliphatic carboxylic acid or dilute mineral acid at temperatures of between room temperature and 100.degree. C., preferably at 40.degree.-70.degree. C.The compounds producible by this method are intermediates for the preparation of 3-keto-.DELTA..sup.4 -6.beta.,7.beta.-methylene steroids constituting pharmacologically valuable compounds, for example aldosterone antagonists.
