In recent years, clean and sustainable mechanochem. solvent-free reactions have emerged as a viable alternative to solution chem. In order to completely solve the problem of environmental pollution caused by solvents and surfactants in LASC and LASSC systems, a green method for the in situ preparation of environmentally friendly inorganic polymeric Lewis acids and silica gel as nanocatalysts (PLASC) under solvent-free mech. grinding conditions was designed and realized by mechanochem. means, which is simple to operate and the process generates no other waste. Subsequently, 3-alkylindole derivatives (35-75%), 尾-amino alc. derivatives (90%), benzimidazole derivatives (85-90%) and quinoxaline derivatives (93-99%) were synthesized by a one-pot cooking method under continuous grinding conditions. The mechanism of in situ self-assembly of PAFC and silica gel on the silica gel surface under mech. forces and the new catalytically active species-Si-O-Al(Fe) polynuclear metal complexes resulting from chem. reforming were discovered and confirmed by SEM, HR-TEM, FT-IR, XRD and XPS tests as well as by solution morphol. studies. The true active center -O-Fe-O-Si-O-/-O-Si-O-Al-O- chem. bonding unit was revealed and found to be a nanoscale fibrous structure that is highly stable and can be reused at least 10 times without deactivation. The PLASC catalyst has remarkable green chem. properties such as easy recycling and a very low E factor, making it a new type of cheap, efficient and green catalyst. In the experiment, the researchers used many compounds, for example, 4-Nitroindole (cas: 4769-97-5Application In Synthesis of 4-Nitroindole).

Synthesis, Conformational Analysis, and Biological Evaluation of 1-Hexylindolactam-V10 as a Selective Activator for Novel Protein Kinase C Isozymes was written by Yanagita, Ryo C.;Nakagawa, Yu;Yamanaka, Nobuhiro;Kashiwagi, Kaori;Saito, Naoaki;Irie, Kazuhiro. And the article was included in Journal of Medicinal Chemistry in 2008.COA of Formula: C8H6N2O2 This article mentions the following:

Conventional and novel protein kinase C (PKC) isoenzymes are the main targets of tumor promoters. We developed 1-hexylindolactam-V10 (I) as a selective activator for novel PKC isoenzymes that play important roles in various cellular processes related to tumor promotion, ischemia-reperfusion injury in the heart, and Alzheimer’s disease. The compound existed as a mixture of three conformers. The trans-amide restricted analogs of I hardly bound to PKC isoenzymes, suggesting that the active conformation of I could be that with a cis-amide. Compound I selectively translocated novel PKC isoenzymes over conventional PKC isoenzymes in HeLa cells at 0.1-1 渭M. These results suggest that I could be useful for the functional anal. of novel PKC isoenzymes. In the experiment, the researchers used many compounds, for example, 4-Nitroindole (cas: 4769-97-5COA of Formula: C8H6N2O2).

A series of substituted indoline and indole derivatives with cyclooxygenase (COX)-inhibitory activity was prepared during our structural development studies based on thalidomide as a multi-template lead compound. Structure-activity relationship studies indicated that the nature of the substituent introduced at the benzene ring of the indoline (indole) backbone, and the length and type of the linking group between the nitrogen atom of indoline (indole) and the N-substituent are important for the activity. This study has led to the identification of COX-1-selective inhibitors, and these should be useful not only as pharmacological tools to investigate the physiology and pathophysiology of COX, but also as sophisticated leads for the development of novel drugs to treat COX-associated diseases, such as inflammatory diseases, and cancer.

The effect of electronic factors on the heterogeneous-catalytic E.Fischer reaction was studied for the case of methoxy- and nitro-substituted arylhydrazones.It was shown that the presence of the methoxy groups in all probability increases the basicity of the respective hydrazone and facilitates adsorption of the active centers of the catalyst.In this case indoles are obtained with high yields.The presence of nitro groups hinder the adsorption of the hydrazone on the catalyst and as a result leads to a decrease in the yield of indole.

Palladium nanoparticles stabilized by lightly cross-linked phosphine-decorated polymer immobilized ionic liquids (PIIL) and their PEGylated counterparts (PEGPIIL) are highly effective catalysts for the aqueous phase hydrogenation and sodium borohydride-based reduction of a wide range of nitroaromatic and heteroaromatic compounds under mild conditions with low catalyst loadings. Introduction of extensive cross-linking with tris(4-vinylphenyl)phosphine to isolate the phosphine-based heteroatom and limit the number of surface Pd?P interactions did not have a significant influence on catalyst performance. Comparative testing revealed PdNPs immobilized on lightly cross-linked phsophine-decoarted PEGylated polymer to be a highly efficient catalyst for the aqueous phase reduction of nitroarenes with a TON of 36000 (TOF = 2580 h-1) for hydrogenation and a TON of 274000 (TOF = 17125 h-1) for transfer hydrogenation. Even though these reactions occur under diffusion control due the poor solubility of the substrate these values are the highest to be reported for the room temperature aqueous phase reduction of nitroarenes catalyzed by a nanoparticle-based system. A continuous flow reduction of nitrobenzene in a packed bed reactor operated over a period of 250 min with no sign of catalyst deactivation and the corresponding space-time-yield of 0.738 g L-1 min-1 is a marked improvement on that of 0.384 g L-1 min-1 obtained in batch. The same system also catalyzes a tandem Suzuki-Miyaura cross coupling-nitroarene reduction sequence to afford high yields of biaryl amine in an operationally straightforward single-pot procedure. This is a highly versatile protocol which will enable the aromatic nitro fragment to be introduced as a nitro-substituted aryl or heteroaryl halide and as such will lend itself to rapid diversification for the synthesis of a wide range of amines.
