Less polar forms and derivatives of 18 hydroxy-corticosterone

The formation of various compounds upon reaction of 18 hydroxycorticosterone with neutral and acid-added alcohols as well as with acidic aqueous solutions is described. The time course of their formation in such media has been studied. Some of these compounds have been isolated and tentatively ident...
