Cationic Pyrrolidine/Pyrroline-Substituted Porphyrins as Efficient Photosensitizers against E. coli
Molecules, 2021 New porphyrin–pyrrolidine/pyrroline conjugates were prepared by revisiting 1,3-dipolar cycloaddition reactions between a porphyrinic azomethine ylide and a series of dipolarophiles.

Synthesis of Spirocyclic Amines by 1,3-Dipolar Cycloaddition of Azomethine Ylides and Azomethine Imines [PDF]
Synthesis, 2020 Simple ketone starting materials with a halide leaving group and an alkene were prepared in one step and heated with glycine or glycine esters to promote a tandem imine formation, cyclization, and dipolar cycloaddition cascade. The chemistry was also feasible with acetylhydrazide.

2′-Methyl-2′-nitro-1′-phenyl-2′,3′,5′,6′,7′,7a'-hexahydrospiro[indoline-3,3′-1′H-pyrrolizin]-2-one
Acta Crystallographica Section E, 2008 The title compound, C21H21N3O3, was synthesized by a multi-component 1,3-dipolar cycloaddition of azomethine ylide, derived from isatin and proline by a decarboxylative route, and (E)-1-phenyl-2-nitropropene.

Synthesis of spiropyrrolizidines containing quinoxaline and pyrrole fragments [PDF]
Известия Саратовского университета. Новая серия: Серия Химия. Биология. Экология, 2023 The reaction of 1,3-dipolar cycloaddition azomethine ylides obtained by the in situ interaction of 11H-indeno[1,2-b]quinoxalin-11-one and proline, and 3-phenyl-1-pyrrolyl-2-en-1-ones has been used for the synthesis of substituted spiropyrrolizidines in ...

Shedding Light on the Chemistry and the Properties of Münchnone Functionalized Graphene
Nanomaterials, 2021 Münchnones are mesoionic oxazolium 5-oxides with azomethine ylide characteristics that provide pyrrole derivatives by a 1,3-dipolar cycloaddition (1,3-DC) reaction with acetylenic dipolarophiles. Their reactivity was widely exploited for the synthesis of

Charge Transport through Conjugated Azomethine-based Single Molecules for Optoelectronic Applications [PDF]
Organic Electronics, 34(2016), 38-41, 2016 The single-molecule conductance of a 3-ring, conjugated azomethine was studied using the mechanically controlled breakjunction technique. Charge transport properties are found to be comparable to vinyl-based analogues; findings are supported with density functional calculations. The simple preparation and good transport properties make azomethine-based

Synthesis and Biological Evaluation of S-, O- and Se-Containing Dispirooxindoles
Molecules, 2021 A series of novel S-, O- and Se-containing dispirooxindole derivatives has been synthesized using 1,3-dipolar cycloaddition reaction of azomethine ylide generated from isatines and sarcosine at the double C=C bond of 5-indolidene-2-chalcogen-imidazolones
