WebReactive intermediates such as nitrenes, carbenes, and radicals have been used in cyclization reactions which produce aziridines and azirines. Intermolecular aziridination reactions with nitrenes were covered in Section 1.01.9.2. Vinylnitrenes ( 118) may undergo cyclization to 2 H -azirines ( 119 ), as shown in Scheme 78. WebReactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI) can damage DNA and several chemical moieties on which its propagation and protection depend, including Fe-S clusters, tyrosyl radicals, hemes, sulfhydryls, thioethers, and alkenes. ROI are produced by all aerobic cells and RNI by many.
