The N-nitrenes generated by oxidation of N-aminoquinazolones (1) and (2) are trapped by the remote 2,4-dimethoxyphenyl ring. Oxidation of (1) in benzene gives the metacyclophane (3) in 60% isolated yield whereas oxidation in methanol gives (5), (6) and (8). The structures of the acetal (5) and the imine (8) have been confirmed by X-ray crystallography. Oxidation of (2) in methanol yields (11) and (16)
