Synthesis of aziridines by electrochemical oxidative annulation of chalcone 1,3-diphenyl-2-propen-1-one with primary amines has been developed under external oxidant - and base-free conditions. The reaction constitutes a new transformation of chalcones with primary amines to aziridines, providing a complementary, simple, and environmentally friendly approach to the currently available methods. A reaction mechanism for this transformation has been proposed based on the cyclic voltammetry.

A novel metal-free allylic C?C σ-bond cleavage of simple olefins to give valuable cinnamyl aldehydes is reported. 1,2-Aryl or alkyl migration through allylic C?C bond cleavage occurs in this transformation, which is assisted by an alkyl azide reagent. This method enables O-atom incorporation into simple unfunctionalized olefins to construct cinnamyl aldehydes. The reaction features simple hydrocarbon substrates, metal-free conditions, and high regio- and stereoselectivity.

Cyclization of N-(propargylic)hydroxylamines catalyzed by AgBF4 afforded the corresponding 4-isoxazolines in good yields. Copper salts were found to promote the further transformation to acylaziridines. The combined use of AgBF4 and CuCl realiz
