Abstract

But, as to the dienone-phenol rearrangement of the steroid В ring55, thorough study is still lacking and the structures of the rearrangement products have remained obscure. Tsuda's group63 was the first to carry out the structural study of a dienone-phenol rearrangement product of the steroid В ring. Namely, 7-keto-5, 8 (9)-cholestadien-3/S-yl acetate (I) 6'", prepared by chromic acid oxidation of 5, 8 (9)-cholestadien-3/3-yl acetate in acetic acid, ...
