Synthesis and characterization of two novel poly(amide-imide)s containing pendent (5-(4,5-diphenyl-1H-imidazol-2-yl)furan-2-yl)phenyl moieties and natural amino acids linkages for adsorption of Cu(II)

Metal/catalyst-free sequential C–N bond forming cascades at room temperature: environment-friendly one-pot synthesis of 5-aminoimidazoles from aryl glyoxals, anilines, and amidines

“…Based on the above results and available literature, 35,55 we propose a plausible mechanistic pathway, as depicted in Scheme 6. The reaction of aryl glyoxal 1 and aniline 2 forms C-benzoylimine intermediate 6 with the loss of two water molecules, which is a very important intermediate for synthetic manipulation.…”

“…[17][18][19][20][21][22] Among nitrogen-containing heterocyclic systems, the imidazole scaffold is one of the most important and ubiquitously found in a variety of compounds, including natural products, amino acids, proteins, alkaloids, pharmaceutical substances, agrochemicals, and functional materials. [23][24][25][26][27][28][29][30][31][32][33][34][35][36] Additionally, imidazoles have provided an imperative contribution as organocatalysts [37][38][39] as well as N-heterocyclic carbene in the field of organic synthesis. 40 The synthesis of amino groups containing imidazoles such as 2-aminoimidazole and their derivatives has been widely explored, as they are easy to synthesize directly from guanidine derivatives, particularly following a desulfurization strategy.…”

A green approach for the catalyst‐free synthesis of imidazole‐bearing pyrazole moiety using PEG‐400 as an efficient recyclable medium as potential anti‐tubercular and anti‐microbial agents

“…Despite recent advances, the development of novel methods for the region‐controlled synthesis of substituted imidazoles is of strategic importance [30]. This is due to the preponderance of applications to which this important heterocycle is being deployed, such as the traditional applications in pharmaceuticals and agrochemicals [31] to emerging research into dyes for solar cells and other optical applications [32], functional materials [33], and catalysis.…”

Recent advances in the synthesis of imidazoles

“…1,2 Despite recent advances, the development of novel methods for the regiocontrolled synthesis of substituted imidazoles is of strategic importance. This is due to the preponderance of applications to which this important heterocycle is being deployed, such as the traditional applications in pharmaceuticals and agrochemicals 3,4 to emerging research into dyes for solar cells and other optical applications, [5][6][7][8][9][10][11][12][13][14][15][16] functional materials, 17 and catalysis 18 (Fig. 1).…”
