Abstract: C4-Symmetrical dirhodium(II) tetracarboxylates are highly efficient catalysts for the asymmetric intermolecular aziridination of substituted alkenes with sulfamates. The reaction proceeds with high levels of efficiency and chemoselectivity to afford aziridines with excellent yields of up… read more here.

DOI: 10.1021/jacs.8b10485
Abstract: In situ deprotection (TFA) of O-Ts activated N-Boc hydroxylamines triggers intramolecular aziridination of N-tethered alkenes to provide complex N-heterocyclic ring systems. Synthetic and computational studies corroborate a diastereospecific aza-Prilezhaev-type mechanism. The feasibility of related intermolecular… read more here.

DOI: 10.5650/jos.ess21406
Abstract: Direct aziridination of a nitrostyrene is achieved upon treatment with an alkylamine and N-chlorosuccinimide. The reaction is initiated by the Michael addition of amine to nitroalkene. Subsequent N-chlorination and nucleophilic substitution at the nitrogen atom… read more here.
