✦ Synopsis

In the title compound, C 25 H 29 NO 2 , ring A adopts a slightly distorted half-chair conformation, while rings B and C are in chair conformations. The ®ve-membered ring D adopts a 13,14-half-chair conformation. The 3-pyridyl ring has an E con®guration with respect to the carbonyl group at position 17. The crystal structure is stabilized by weak intra-and intermolecular CÐHÁ Á ÁO interactions and van der Waals forces.

Different mutants of the catabolism of androst-4-ene-3,17-dione were produced in Nocardia restricta by action of y-rays and nitrosoguanidine. These selected mutants (acetate+-undrost-4-ene-3,17-dione-) are hexanoate-. Their behaviour is identical to the mutants selected as hexanoateacetatet which ar
