Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 2935-35-5, Name is H-Phg-OH, SMILES is O=C(O)[C@@H](N)C1=CC=CC=C1, belongs to phthalazine compound. In a document, author is Soltanzadeh, Zahra, introduce the new discover, COA of Formula: https://www.ambeed.com/products/2935-35-5.html.

In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2935-35-5 is helpful to your research. COA of Formula: https://www.ambeed.com/products/2935-35-5.html.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 66-99-9, Name is 2-Naphthaldehyde, SMILES is O=CC1=CC=C2C=CC=CC2=C1, in an article , author is Turkes, Cuneyt, once mentioned of 66-99-9, Name: 2-Naphthaldehyde.

The synthesis, characterization and biological evaluation of a series of novel N-substituted phthalazine sulfonamide (5a-1) are disclosed. Phthalazines which are nitrogen-containing heterocyclic compounds are biologically preferential scaffolds, endowed with versatile pharmacological activity, such as anti-inflammatory, cardiotonic vasorelaxant, anticonvulsant, antihypertensive, antibacterial, anti-cancer action. The compounds were investigated for the inhibition against the cytosolic hCA I, II and AChE. Most screened sulfonamides showed high potency in inhibiting hCA II, widely involved in glaucoma, epilepsy, edema, and other pathologies (K(i)s in the ranging from 6.32 +/- 0.06 to 128.93 +/- 23.11 nM). hCA I was inhibited with K(i)s in the range of 6.80 +/- 0.10-85.91 +/- 7.57 nM, whereas AChE in the range of 60.79 +/- 3.51-249.55 +/- 7.89 nM. ADME prediction study of the designed N-substituted phthalazine sulfonamides showed that they are not only with carbonic anhydrase and acetylcholinesterase inhibitory activities but also with appropriate pharmacokinetic, physicochemical parameters and drug-likeness properties. Also, in silico docking studies were investigated the binding modes of selected compounds, to hCA I, II, and AChE.

In the recent decades, N-heterocycles are widely used as versatile scaffolds for the development of biologically active compounds and considered as one of the privileged structures. Among the various N-heterocycles, benzodiazines, a series of bicyclic heterocycles in which benzene rings are fused with 6-membered heterocycles containing two nitrogens are especially interesting, due to their structural conciseness and usefulness as synthetic intermediates, and suitable physicochemical properties as potential drug candidates and chemical probes. For this reason, a series of synthetic methodologies for benzodiazines has been developed and generally used in organic and medicinal chemistry fields. Interestingly, synthesis of quinazoline, a kind of benzodiazine in which benzene is fused with pyrimidine, has been extensively reviewed, while cinnoline, phthalazine and quinoxaline, benzene fused with pyridazine or pyrazine, have been relatively less investigated. In this review, recent advances in the synthesis of biologically active benzodiazines, benzene ring-fused 6-membered heterocycles with two nitrogen atoms, cinnoline, phthalazine and quinoxaline, will be addressed. In each section, biological activities of various benzodiazines, recently served as novel scaffolds for drug discovery, are briefly summarized for comprehensive understanding of biological and medicinal significance in advance. Moreover, intensive investigation of the synthetic approaches to various benzodiazines such as cinnoline, phthalazine and quinoxaline is followed. It would hopefully be helpful for the readers who have interests in developing novel drug candidates and related useful chemical probes.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Application In Synthesis of p-Isopropylbenzenecarboxaldehyde, 122-03-2, Name is p-Isopropylbenzenecarboxaldehyde, SMILES is CC(C)C1=CC=C(C=O)C=C1, in an article , author is Wedek, Volker, once mentioned of 122-03-2.

The use of a new class of unsymmetrical cinchona-alkaloid-based, phthalazine-bridged organocatalysts enabled the highly enantioselective dichlorination of unfunctionalized alkenes. In combination with the electrophilic chlorinating agent 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) and triethylsilyl chloride (TES-Cl) as the source of nucleophilic chloride, 1-aryl-2-alkyl alkenes were dichlorinated with enantioselectivities of up to 94:6 er. Initial mechanistic investigations suggest that no free chlorine is formed, and by replacement of the chloride by fluoride, enantioselective chlorofluorinations of alkenes are possible.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 122-03-2, you can contact me at any time and look forward to more communication. Application In Synthesis of p-Isopropylbenzenecarboxaldehyde.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 122-03-2, Name is p-Isopropylbenzenecarboxaldehyde, molecular formula is C10H12O, belongs to phthalazine compound. In a document, author is Kiasat, Ali Reza, introduce the new discover, COA of Formula: https://www.ambeed.com/products/122-03-2.html.

A simple, efficient, and high yielding one-pot protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives has been developed by three-component coupling of phthalhydrazide, dimedone and some aromatic aldehydes in ecofriendly neat conditions promoted by nano-gamma-alumina sulforic acid. This protocol avoids the use of expensive catalysts, toxic solvents and chromatographic separation. Also the proposed protocol was extended to the linear beta-diketone (acetylaceton) instead of cyclic diketone (dimedone). The generality and functional tolerance of this convergent and environmentally benign method is demonstrated. The nature of each step of the suggested mechanism for this condensation reaction is also identified through Density Functional Theory (DFT) calculations using B3LYP/6-31G** level of theory. It is shown that the first step is charge controlled; whereas the second one is controlled by frontier molecular orbitals. The H-1 and C-13 chemical shift values together with the structural parameters of the title compound have been also computed and the scaled values have been compared with the corresponding experimental NMR and X-ray spectra. As a result, the calculated spectroscopic data and optimized geometry show a good agreement with the experimental results. (C) 2012 Elsevier B.V. All rights reserved.

In a document, author is Iravani, Nasir.

A novel heteropolyanion-based Bronsted acidic ionic liquid material [PhBS](3)PW12O40, butane mono-sulfoacid-functionalized phenanthrolinum salt of phosphortungstate catalyst (PhBS-PW), was synthesized and well characterized with FTIR, H-1 and C-13 NMR, electro-spray ionization mass spectrometry (ESI-MS), EDX and TG analysis techniques. The new prepared catalyst was used for the efficient one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives from a three-component condensation reaction between aromatic aldehydes, dimedone, and phthalhydrazide in H2O under thermal conditions. This green approach has several advantages such as short reaction times, clean reaction profiles, and simple experimental and workup procedures. Moreover, the catalyst can be easily recovered and reused at least nine times with only slight reduction in its catalytic activity with no leaching amount of catalyst into the reaction mixture. These economical factors (time, cost, waste, etc.) for this three-component reaction hold promise for the future of organic synthesis. Graphic abstract In this work we introduced a new efficient Bronsted acidic ionic liquid (BAIL) and then its catalytic activities have been considered in the three-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones via the domino Knoevenagel condensation/Michael addition/intramolecular cyclodehydration sequence in water under reflux condition.
