Reactivity of α,α-Dihalogenated Imino Compounds. Part VIII1. Aziridine Formation by Lithium Aluminium Hydride Reduction of N-2-(1,1-Dichloroalkylidene) Cyclohexylamines

1,2-Disubstituted aziridines 2 are not readily accessible and most syntheses remain laborious3. We recently reported4 that reaction of α,α-dihalogenated aldimines with lithium aluminium hydride provided a facile synthesis of 1,1-disubstituted aziridines (a three step synthesis starting from ordinary aliphatic aldehydes).
