| titleOfInvention | Preparation of intermediate for preparing corticoid |
| abstract | PURPOSE: To obtain the titled intermediate for preparing adrenocortical hormones in short steps, by bringing a novel dihalogenated steroid obtained from androsta-4,9(11)-diene-3,17-dione, etc. into contact with a metallic powder, e.g. zinc or iron. n CONSTITUTION: A novel dihalogenated steroid, e.g. 17α-dihydroxy-21,21-dibromopregna-1,4-diene-3,20-dione 17-acetate, of formulaI(the dotted line is single or double bond; X is halogen; Y is acyloxy) obtained from androsta-4,9(11)-diene- 3,17-dione easily derived from 9α-hydroxyandrost-4-ene-3,17-dione as a raw material is brought into contact with a metallic powder, e.g. zinc or iron, in a molar amount of preferably 5W20 times that of the dihalogenated steroid to give the aimed pregnane steroid of formula II. n USE: Useful as a leuteohormone itself. n COPYRIGHT: (C)1982,JPO&Japio |
