STEROIDS X AROMATIZATION EXPERIMENTS IN THE CHOLESTEROL SERIES

Abstract

Aromatization of a tetralin solution of 1,4,6-cholestatrien-3-one (V) at 700° produced 3-hydroxy-19-nor-1,3,5,6-cholestatetraene (VI), which on hydrogenation led to the phenol VII, an analog of cholesterol possessing an aromatic ring A. Both phenols were
