Background: The reactivity of 4-(dicyanomethylene)-3-methyl-l-phenyl-2-pyrazoline-5-one DCNP 1 and its derivatives makes it valuable as a building block for the synthesis of heterocyclic compounds like pyrazolo-imidazoles, – thiazoles, spiropyridines, spiropyrroles, spiropyrans and others. As a number of publications have reported on the reactivity of DCNP and its derivatives, we compiled some features of this interesting molecule. Objective: This article aims to review the preparation of DCNP, its reactivity and application in heterocyclic and dyes synthesis. Conclusion: In this review we have provided an overview of recent progress in the chemistry of DCNP and its significance in synthesis of various classes of heterocyclic compounds and dyes. The unique reactivity of DCNP offers unprecedentedly mild reaction conditions for the generation of versatile cynomethylene dyes from a wide range of precursors including amines, a-aminocarboxylic acids, their esters, phenols, malononitriles and azacrown ethers. We anticipate that more innovative transformations involving DCNP will continue to emerge in the near future.

The promising application of deuterium-labeled compounds, such as the drug deutetrabenazine, warrants efficient, selective, and direct deuteration of organic entities. Here, we present a highly effective regioselective direct C-H deuteration of indole in D2O using Cp*Co(CO)I-2, [Cp*RhCl2](2), or their combination as a catalyst. This transition-metal-catalyzed system made available DG mono(C2)-, di(C2/C7)-, tri(C2/C3/C7)-, and even C4-deuterated products from diverse indole substrates, equipped with the removable N1-directing group. The selective H/D exchanges on the rest of the sites of the indoles were also realized by shifting the directing group. Furthermore, an example of this approach was demonstrated to acquire deuteromelatonin from the drug melatonin.

Indole based heterocyclic molecules are important and valuable structural unit that are present in various biologically active natural products, pharmaceuticals and agrochemicals. In this paper, zinc oxide nanoparticles were explored as catalyst for the synthesis of 3-substituted indoles in water via ultra-sonication. The stability of ZnO nanoparticles and their dispersion in water was enhanced by grafting it with a biodegradable polymer (poly lactic acid). The proposed methodology is capable of providing desired products in good yield (83-97%) and 25 derivatives of indoles were synthesized. The green reaction metrics such as E-factor (0.16) and atom economy (97%) show that the present protocol is sustainable and economical. Also, the reactions were carried out in water under environmentally benign conditions that avoids use of any additives or hazardous solvents.

An N-2-fixing bacterium, Ensifer meliloti CGMCC 7333, has been reported to degrade the cyano-containing neonicotinoid insecticides acetamiprid and thiacloprid using a nitrile hydratase (NHase). Here, the bioconversion of indole-3-acetonitrile (IAN) by E. meliloti, Escherichia coli overexpressing the NHase, and purified recombinant NHase was studied. E. meliloti converted IAN to the product indole-3-acetamide (IAM), and no nitrilase or amidase activities, or indole-3-acetic acid formation, were detected. Whole cells of E. meliloti converted IAN from the initial content of 6.41 to 0.06 mmol/L in 48 h. Meanwhile, forming 5.99 mmol/L IAM, the molar conversion of 94.4%. E. coli Rosetta overexpressing the NHase from E. meliloti produced 4.46 mmol/L IAM in 5 min, with a conversion rate of 91.1%. The purified NHase had a V-max for IAN conversion of 294.28 U/mg. Adding 2% and 10% (v/v) dichloromethane to 50 mmol/L sodium phosphate buffer containing 200 mg/L IAN increased the NHase activity by 26.8% and 11.5% respectively, while the addition of 20% hexane had no inhibitory effect on IAN bioconversion. E. meliloti shows high NHase activity without forming a byproduct carboxylic acid, and its tolerance of dichloromethane and hexane increases its potential for application in the green biosynthesis of high-value amide compounds.

In a document, author is Gao, Mengying.

A Rhodium-catalyzed C2-H functionalization of indoles with diazo compounds, followed by intramolecular nucleophilic addition to C=O or C=C bonds, is reported for divergent synthesis of 2,3-fused indoles. Besides acceptor/acceptor diazo compounds, donor/acceptor diazo compounds are broadly tolerated, giving various 2,3-fused indoles with perfect diastereocontrol. Notably, a selective C-H dialkylation reaction at C2 and C7 position of indoles has also been developed by simply changing the reaction conditions. This environmentally benign transformation proceeds under mild conditions and gives dinitrogen as the only by-product.
