DJERASSI, et al. (1) have pointed out that the optical rotatory dispersion (ORD) curve in substituted-A 4 -3-ketosteroids reflects conformational distortions in the B-ring rather than in the A-ring. Their conclusion is based on the observation that 17@-acetoxyandrost-4-en-3-one and its 2,2-dimethyl

THE ground state oouformations of the steroid ring systems are in general securely looked in potential wells, can vary but little, and are for the most part well understood. In a 4,4-dimethyl-3-keto-5gC-steroid (I) however, there is reason to question whether or not ring A will be in the standard ch
