| titleOfInvention | Recycling method of 3 beta-acetoxyandrostane-5-alkene-17-ketone addition reaction byproduct |
| abstract | The invention discloses a method for preparing 3 beta-acetoxyl-5 alpha-chlorine-6 beta-hydroxyandrost-17-ketone by using solid waste 3 beta-acetoxyl-6 alpha-chlorine-5 beta-hydroxyandrost-17-ketone in the addition reaction process of 3 beta-acetoxyl androst-5 alpha-chlorine-6 beta-hydroxyandrost-17-ketone as a raw material and preparing the 3 beta-acetoxyl-5 alpha-chlorine-6 beta-hydroxyandrost-17-ketone through two-step reactions of eliminating cyclization and addition ring opening. The method can effectively recycle the by-product in the preparation process of the 3 beta-acetoxyl-5 alpha-chlorine-6 beta-hydroxyandrostan-17-ketone, is environment-friendly and reduces the production cost. The method for preparing the 3 beta-acetoxyl-5 alpha-chlorine-6 beta-hydroxyandrost-17-ketone has the advantages of simple and convenient operation, mild reaction condition and high yield. |
