“…Despite work reported on the synthesis of ketoaziridines, novel and widely applicable methods for the synthesis of them are still in demand. Throughout our earlier studies on the ketoaziridines [30][31][32][33][34][35][36][37], to further develop aziridination reaction, we have discovered a simple and stereo-selective one-pot method for the synthesis of ketoaziridines by the reaction of chalcones with 1-aminopyridinium iodide via in situ formation of N-N ylide. This method describes a novel method which for the first time utilizes 1-aminopyridinium iodide for the synthesis of aziridine in a one-pot reaction.…”

by bromination of the related α,β-unsaturated carbonyl compounds, followed with the reaction of ammonia solution [5][6][7][8][9][10].Another synthetic pathway for the synthesis of aziridinyl ketones involves formation of β-hydroxyamino derivatives followed by treatment with either metal alcoholates, or hydroxylamine hydrochloride and then potassium hydroxide [11][12][13][14]. It has been reported the interaction of unsaturated ketones with N-tosyliminoaryliodinanes in the presence of mono-valent copper complexes produces the related aziridinyl ketone [15,16].It was also reported that oximes could be converted into N-unsubstituted aziridines by treatment with Grignard reagents or by reduction with lithium aluminum hydride in certain cases [17].3,3-Pentamethyleneoxaziridine can transfer its NH group to electron-deficient olefins to give N-unsubstituted aziridines in low yields [17,18]. 2-ketoaziridine starting materials were also prepared using 1,4-addition of methoxyamine to α,β-unsaturated ketones followed by basepromoted ring closure [19]. Ylides are another kind of potential NH transfer agent. Free sulfimides HN = SR 2 , sulfur-nitrogen ylide [20][21][22][23][24], are used for the direct synthesis of N-unsubstituted aziridines. An one step synthesis of aziridine by the type addition off free sulfimide has been reported but yields are unsatisfactory and enaminoketones are obtained as major byproducts in moderate yields.On the other hand, an amineimide, as a type of nitrogennitrogen ylide, is an effective NH source for direct N-unsubstituted aziridination of electron-deficient olefins. Recently, a few method has been reported that tertiary amines such as N-methylmorpholin [25], 1,4-diazabicyclo[2.2.2]octane (DABCO) [26,27]. Quinine chiral tertiary amine [28] and Troger s base [29] can prepare amine imide which reacts with chalcone to give desire aziridinyl ketones (Scheme 1).Abstract A new approach for the synthesis of N-H ketoaziridines is described. 1-aminopyridinium iodide as a NH transferring agent provides a straightforward access to the 2-aroyl-3-arylaziridines from the corresponding 1,3-diarylprop-2-en-1-one. A possible general mechanism involving the N-N ylide is proposed.

“…[9][10][11] We have explored different reactions of 2-aroyl-3-aryl aziridines affording functionalised and other valuable N-containing compounds. [12][13][14][15][16][17][18][19][20] In continuation of our research activities in the field of the reactions of aziridines, we have found that N-bromosuccinimide (NBS)/cerium (IV) ammonium nitrate (CAN) is a suitable reagent for deamination of N-H, N-aryl and N-aroyl 2-benzoyl-3-phenyl aziridines. This study shows that substituents on C1 and C2 aziridines have a more important role in determining the reactions, deamination or oxidation, with NBS/CAN rather than substituents on the N-atom of the aziridine ring.…”

An efficient and novel method for the deamination of trans-1-alkyl (H or benzoyl)-2-aroyl aziridines in a completely stereocontrolled reaction in the presence of N-bromosuccinimide/cerium (IV) ammonium nitrate is described. In comparison with the previous reported work, this reaction reveals a substituent-reactivity relationship and important role for the substituent on C1 and C2 in determining whether deamination or oxidation reaction takes place.
