| abstract | PURPOSE: To obtain an adrenocortical hormone in short steps, by reacting a novel 17β-ethynylsteroid obtained from androsta-4,9(11)-diene-3,17-dione, etc. with water in the presence of a mercury compound. n CONSTITUTION: A novel 17β-ethynylsteroid, e.g. 17β-ethynyl-17α-hydroxyandrosta- 1,4-dien-3-one, etc. of formulaI(the dotted line is single or double bond), 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 reacted with water in the presence of a mercury compound, e.g. mercuric chloride or mercuric oxide, in a molar amount of preferably 0.5W5 times that of the ethynylsteroid, at preferably 30W70°C to give the aimed compound of formula II. n COPYRIGHT: (C)1982,JPO&Japio |
