Thermally induced opening of the diaziridine ring at the carbon-nitrogen bond in unsymmetrically substituted 6-aryl-1,5-diazabicyclo[3.1.0]hexanes is characterized by low regioselectivity which is likely to be determined by the inductive effect of substituents in the trimethylene bridge. 1,3-Dipolar cycloaddition of the resulting azomethine imines to phenyl isocyanate is regioselective: it occurs at
