Abstract

Ultraviolet irradiation of Δ1-dehydro-O-acetyl-testosterone (I) yields a mixture of ketonic and phenolic substances. Two of the phenols have been identified as 1-methyl-oestradiol-17-acetate (VIII) and 4-methyl-1-hydroxy-17 β-acetoxy-oestratriene-(1,3,5:10) (X). A preliminary report is given on the nature of two additional phenolic products as well as of 4 ketones, isomeric with compound I.
