Oxidation of N-aminoquinazolones in the presence of alkenes: evidence against involvement of N-nitrenes
Abstract
Solutions of 2-ethyl-3-acetoxyamino-4(3H)-quinazolone (6) have been obtained by oxidation of the corresponding 3-aminoquinazolone (4) with lead tetra-acetate at –20 °C; (6) brings about aziridination of alkenes by a mechanism that does not involve N-nitrene or N-nitrenium ion intermediates.
