title: Steroid 19,B-dinor-8,10-iso-analogues.
abstract: The Birch reduction of 3-methoxy-B-nor-8-isoestra-1,3,5(10)-trienes followed by acid hydrolysis produces steroid androgen 19,B-dinor-8,10-iso-analogues. By means of X-ray analysis and correlation NMR spectroscopy of 16,16-dimethyl-D-homo-19,B-dinor-8-isotestosterone, C(20)H(30)O(2), it is demonstrated that the main conformations in the crystal and in solution for two 19,B-dinor-8,10-iso-analogues are, in general, the same.
