Cavitands are synthetic receptors typically based on resorcin[4]arenes, macrocyclic concave compounds that are readily available and can be easily transformed into deeper synthetic cavities by attachment of aromatic spacers or panels. The use of aromatic heterocycles is ubiquitous in these structures, either for synthetic convenience, to regulate the dynamic and self-assembling properties of these receptors, or to provide suitable coordination environments for metal-functionalized receptors.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, COA of Formula: C8H4Cl2N2, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 2213-63-0

Nitrosation (NaNO2/AcOH) of 2-phenylindoles (1a-d) and subsequent reduction of the resultant 3-nitroso-2-phenylindoles (2a-d) with sodium dithionite in alkali furnish the corresponding 3-aminoindoles (3a-d), which on condensation with ethyl chloroformate in pyridine give ethyl 2-phenylindole-3-carbamates (4a-d).The compounds 4a-d undergo smooth condensation with hydrazine hydrate (80percent) in ethanol to give 2-phenylindole-3-semicarbazides (5a-d).These semicarbazides when treated with sodium nitrite and acetic acid, the azides formed undergo spontaneous decomposition to give nitrenes which on cyclisation yield 1,2,3,8-tetrahydroindololo<5,4-b><1,3>benzodiazepin-2-ones (6a-d).Ethyl 3-phenylindole-2-carboxylates (8a-f) on treatment with hydrazine hydrate (80percent) in ethanol give the corresponding carbohydrazines (9a-f), which on reaction with sodium nitrite in acetic acid followed by refluxing the resultant acyl azides (10a-f) with anhyd. ethanol furnish ethyl 3-phenylindole-2-carbamate (11a-f). 3-Phenylindole-2-semicarbazides (12a-f), obtained in good yield from the respective carbamates by refluxing with hydrazine hydrate in ethanol, on reaction with NaNO2/AcOH afford 5,6,7,8-tetrahydroindolo<4,5-b><1,3>benzodiazepin-6-ones (13a-f).

New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.Synthetic Route of 1448-87-9, In a article, mentioned the application of 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2

In this investigation, quinoxaline derivatives namely, 2-(5-(2-chlorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (CPTQ) and 2-(3,5-diphenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (DPTQ) were synthesized and applied as corrosion inhibitors for mild steel (MS) in15% HCl solution. The corrosion inhibition behaviour of CPTQ and DPTQ was studied through weight loss measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The maximum corrosion inhibition efficiency of DPTQ and CPTQ was found to be 96.01 and 95.62%, respectively at 100 ppm concentration and 303 K temperature. Potentiodynamic polarization studies showed that CPTQ and DPTQ act as mixed type inhibitors. Surface morphology of uninhibited and inhibited MS specimens was characterized using AFM and SEM studies. DFT, molecular dynamic simulations and calculation of Fukui functions were performed for correlation of theoretical parameters with the experimental results.
