Tetraalkylaziridines are three-membered nitrogen-containing heterocycles in which the nitrogen atom is substituted with alkyl groups. Their synthesis can be achieved by several methods, primarily involving intramolecular cyclization of suitable precursors. One of the common approaches is the nucleophilic substitution reaction of haloamines or β-haloamines. In this method, a tertiary amine with a leaving group at the β-position undergoes an intramolecular nucleophilic attack, forming the aziridine ring. For example, N,N-dialkyl-2-haloethylamines can cyclize under basic conditions to give tetraalkylaziridines. Bases such as sodium hydride, potassium
