| titleOfInvention | Preparation of 17alpha-hydroxyprogesterone derivative |
| abstract | PURPOSE: To obtain the titled compound useful as an intermediate for a luteohormone, etc. industrially and advantageously, by reacting a specific 17β-cyano- 17α-hydroxyandrost-4-en-3-one, etc. with a methyl metallic compound, and hydrolyzing the resultant reaction product. n CONSTITUTION: (A) 17β-Cyano-17α-hydroxyandrost-4-en-3-one or 17β-cyano-17α- hydroxyandrosta-4,9 (11) -dien- 3-one in which the carbonyl group at the 3-position and the hydroxyl group at the 17α-position are protected is reacted with (B) a methyl metallic compound expressed by the formula CH 3 X (X is lithium atom or halomagnesium), e.g. methyl lithium, at -30W+100°C, and the resultant reaction product is then hydrolyzed to give the aimed compound. n COPYRIGHT: (C)1982,JPO&Japio |
