Process for the preparation of 17α-hydroxy- and 17aα-hydroxy-D-homoetiocarboxylic acids |
| abstract |
17α-hyroxy- and 17aα-hydroxy-D-homoetiocarboxylic acids of the formula ##STR1## wherein n is 1 or 2, n A is ##STR2## and R 1 is H or CH 3 n are prepared by hydrating the corresponding 17-nitriles with a mixture of a lower carboxylic acid and its anhydride in the presence of perchloric acid. The resultant 17β-N-acylcarboxamide is then treated with an alkali metal hydroxide in a polyhydric alcohol at an elevated temperature. The product acids are intermediates, e.g., for the production of steroids having antiinflammatory activity. |
