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
