The oxidation of the A-secolanosterol derivative 3-nitrilo-3,4-secolanosta-4(30),8-diene (IV) by mercuric acetate has produced the aromatic compound A-seco-1,2,3-trisnorlanosta-4(30),5(10),6,8-tetraene (VIII). When the cyanide group in (IV) was replaced by CO2H, CO2Me, or CONH2, the reaction did not occur. The aromatisation reaction also failed if the isopropenyl group was reduced [as in (IX)] or when
