Nucleophilic addition to 3-methyl-1-(4-nitrophenyl)-2-phenyl-4,5-dihydroimidazolium iodide

Reactions of the 1,2-diaryl 4,5-dihydroimidazolium, represented by 3-methyl-1-(4-nitrophenyl)-2-phenyl-4,5-dihydroimidazolium iodide 1, with ethylenediamine afforded a benzylidyne unit transferred product, 2-phenyl-2-imidazoline 2; a ring-opened adduct 4 was produced when excess ethylenediamine was used. Reactions of 1 with hydroxylamine, malononitrile, and nitromethane anions produced ring-opened products, 5, 7, and 8 respectively.

Visible Light-Promoted Aryl Azoline Formation over Mesoporous Organosilica as Heterogeneous Photocatalyst

N-heterocyclic compounds demonstrate wide applications ranging from natural compound production to coordination chemistry. Usually, the synthesis of N-heterocyclic compounds is conducted under thermal conditions, mostly by Lewis acids or metal-containing compounds as molecular catalysts. Here, we report a photocatalytic route for aryl azoline formation by mesoporous organosilica as visible light-active and heterogeneous photocatalyst. Via formation of aromatic aldehydes with various amines, 2-phenyl-2-imidazoline, 2-phenyl-2-oxazoline, 2-phenyl-2-thiazoline and their derivatives could be formed with high conversion and selectivity. Additionally, the organosilica photocatalyst showed high stability and reusability.

Electrophilically activated nitroalkanes in reaction with aliphatic diamines en route to imidazolines

A novel synthetic methodology for the assembly of imidazolines via an unusual reaction between nitroalkanes and aliphatic 1,2-diamines in the presence of phosphorous acid is described. In contrast to the related highly efficient preparation of benzimidazoles from aromatic amines, this process represents a major synthetic challenge and for a long time was elusive. Analysis of the method limitations is provided.
