Studies on the Partial Synthesis of Corticosterone. I BY PURNENDU NATHCHAKRAVORTY~ AND EVERETT S. WALLIS Through the pioneering investigations of Rogaff,* Swingle3 a.nd Hartman4 the existence of a powerful hormone in the adrenal gland, other than adrenalin, was established. The method of Swingle and Pfiffner5 for the preparation of concentrates of this hormone has been widely used, and has culminated in the isolation of several crystalline products, notably by three groups of investigators led by Reichstein'j a t Zurich, Kendall' a t the Mayo Clinic and Wintersteinera a t Columbia University. Among these crystalline materials which have been isolated some have been found to be inactive and the structures of the few physiologically active compounds are still uncertain on certain points. Corticosterone, the most potent of the crystalline compounds, has been assigned formula I. CH20H I
