An efficient synthesis of non-activated 2-(chloromethyl) aziridines and 2-chloromethyl-2- methylaziridines as new representatives of the class of 2-(halomethyl) aziridines was developed. Furthermore, the reactivity of these azaheterocycles was assessed and compared to that of their brominated counterparts, pointing to a similar profile for 2- (chloromethyl) aziridines and 2-(bromomethyl) aziridines on the one hand, and a different ...
