Fused aziridines as sources of azomethine ylides
The use of fused aziridines as sources of azomethine ylides in the synthesis of polyheterocyclic compounds is examined. Features of thermo- and photolytic opening of aziridines and aspects of the stereo-, regio-, and chemoselectivity of cycloaddition and electrocyclization of azomethine ylides are discussed.
