Aziridination by oxidative addition of -aminoquinazolones to alkenes: Evidence for non-involvement of -nitrenes

摘要: Abstract Oxidation of 3-aminoquinazolones e.g. (22) with lead tetra-acetate at −20°C gives N -acetoxyaminoquinazolones (23) which are stable in solution this temperature. These function as inter- and intramolecular aziridinating agents for alkenes appear to be playing the role previously ascribed corresponding -nitrenes. An analogous -acetoxyaminophthalimide intermediate (31) is implicated oxidation -aminophthalimide (4).
