2‐aryl‐3‐(2‐cyanoethyl)aziridines were deployed as substrates for an In(OTf)3‐mediated regio‐ and stereoselective ring rearrangement upon treatment with LiAlH4, affording a variety of novel 2‐(aminomethyl)pyrrolidines and 3‐aminopiperidines, respectively. Further synthetic elaboration of the obtained 3‐aminopiperidines resulted in the formation of a peculiar and unexplored conformationally constrained
