6-Phenylazocholestane derivatives: reassignment of the structures of products from phenylhydrazine and ozonised cholesterol derivatives
Abstract
The reaction of phenylhydrazine with ozonised cholesteryl acetate has been reported to yield a product in which ring B is expanded to an eight-membered ring. This structure is shown to be incorrect, the true structure being 3β-acetoxy-6α-phenylazocholestan-5α-ol. Comparisons are made with related reactions in the carbohydrate field.
