✦ Synopsis
Novel Enone-Benzene Rearrangement of 4,4-Dialkylcholest-5-en-3-ones to Ring-B Aromatic Steroidal Hydrocarbons Catalyzed by p-Toluenesulfonic Acid.
-Reinvestigation of the acid-catalyzed enone-benzene rearrangement of 4,4-disubstituted cholestenones such as (I) by employing TosOH as catalyst is reported. New by-products (III) having an aromatic B-ring are identified. -(DUAN, HUI-YUN; LI, TONG-SHUANG;
