Thebaine (1) reacts in methanol with tetranitromethane to give, as the major product, 14β-nitrocodeinone dimethyl acetal (2a), which has been converted into, inter alia, 14β-nitrocodeinone (3a), 14β-aminocodeinone dimethyl acetal (2b), 14β-aminocodeinone (3b), and 14β-aminocodeine. The nitration of thebaine with tetranitromethane in benzene in the presence of oxygen takes a different course. The major
