Synthesis of 6-Amino- and 6-Hydroxy-1-Aryl-2-(Thiazol-2-Yl)-9-(2-Thienoyl)-1,2-Dihydro-3H-Pyrrolo[3,4-B]Quinolin-3-Ones

5-aryl-3-hydroxy-1-(thiazol-2-yl)-4-(2-thienoyl)-1,5-dihydro-2H-pyrrol-2-ones were found to react with meta-phenylenediamine or 3-aminophenol forming pyrrolo[3,4-b]quinolin-3-ones. Using 4-amino-phenol and 3-methoxyaniline as reagents led to the formation of 3-arylamino derivatives.

Conjugate addition reactions of alpha-aminoalkylcuprates with alpha,beta-alkenyl-, alpha,beta-alkynyl-, alpha,beta-beta,gamma-allenyl-, and alpha,beta-gamma,delta-dienyl carboxylie acid derivatives, nitriles, and sulfoxides

alpha -Aminoalkylcuprates prepared from alpha -lithio carbamates and CuCN.2LiCl participate in 1,4-addition reactions with alpha,beta -unsaturated esters, thiol esters, imides, and nitriles in poor to excellent yields depending upon the electron-withdrawing substituent and the substitution pattern of the unsaturated substrate. These reagents also undergo conjugate addition reactions with alpha,beta -alkynyl esters, sulfoxides, and nitriles and with alpha,beta-beta,gamma -unsaturated allenyl esters. Excellent stereocontrol is achieved in the conjugate additions of alpha -aminoalkylcuprates to the allenyl esters, while poor stereoselectivity results in the conjugate additions to the alkynyl derivatives. Deprotection and cyclization of the alkynyl adducts affords pyrrolin-2-ones, while similar treatment of the allenyl adducts affords 4-alkylidine- pyrrolidin-2-ones and pyrrolizidinones.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 293298-33-6, you can contact me at any time and look forward to more communication.

Preliminary studies towards the preparation of reactive 3-pyrrolin-2-ones in conjugate addition reactions for the syntheses of potentially bioactive 2-pyrrolidinones and pyrrolidines

Pyrrolin-2-ones and 2-pyrrolidinones are moieties often found in the structure of several biologically active natural products and 3-pyrrolin-2-ones are valuable starting materials in organic synthesis due to their ability to react as acceptors in conjugate addition reactions. In this article we report the initial results about the performed study aiming at the syntheses of reactive 3-pyrrolin-2-ones in conjugate addition reactions and the preparation of a potential precursor for the synthesis of the nootropic (+/-)-nebracetam.

A comparative study on mechanical and rheological properties of ternary rubber blends

Polymer blends lead to producing a new class of plastics, which may have better properties than being individual. In this study, the ternary blends of natural rubber (NR)/styrene-butadiene rubber (SBR)/nitrile rubber (NBR) were prepared via melt compounding, and then the physicomechanical properties of ternary NR/SBR/NBR blends were investigated. NR content was kept constant at 30 phr, while SBR and NBR fractions were varied simultaneously. The effect of the addition of 3 phr of ultrablend 4000 as compatibilizer on the compatibility of the rubber blends was studied. The results revealed that the use of the compatibilizer has significantly resulted in the clear stability of the scorch time and the optimum cure time of the blends. Tensile strength; stress at 100%, 200%, and 300% elongations; elongation at break %; compression strength; and compression set increase with the NBR content. There was a dramatic rise in the value of swelling ratio with the decrease of NBR. Moreover, the dynamic mechanical analysis showed some shifts in glass transition temperatures for blends to higher and lower temperatures as a function of the composition, which indicates the partial miscibility between the contributing components. Scanning electron microscopy of the tear fracture surfaces indicated that incorporation of NBR in the blends resulted in better adhesion of ternary blends and improved the tensile properties of ternary blends.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 293298-33-6, you can contact me at any time and look forward to more communication. Category: pyrrolines.

Recent advances in C-CN and C-H bond activation of green nitrile (MeCN) for organo-complexation, cyanation and cyanomethylation

The use of green and inexpensive organic nitrile (MeCN) as a cyano and cyano-methyl source for organo-complexation, cyanation, and cyanomethylation is reviewed. In recent decade, a lot of developments have been made to realize the possibility of using a green cyanide source (MeCN) for cyanation, and this CN source has been used as, for example, a slow dosage cyanide source that could solve the problem of using metal cyanides (K-4[Fe(CN)(6)], Zn(CN)(2), KCN, CuCN, NaCN), which (1) tend to cause rapid deactivation of the catalyst and (2) are notoriously toxic, producing highly toxic HCN gas in reactions. In view of these problems, here we attempted to discuss new catalyst systems to achieve the cyanation of various aromatic hydrocarbons, such as aryl halides, aryl boronic acids, aryl carboxylic acids, indoles, diazoarenes, aryl alkynes, aryl sulfonamides, and directing group substituted arenes, under variety of reaction parameters. Moreover, acetonitrile is used as the carbon pro-nucleophile in C-C bond formation, which involves complications usually associated with the catalyst active mode or its resting state. This review demonstrates a set of innovations for practical usageviadirect complexation, cyanation and cyanomethylation methodologies.

Application of 293298-33-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 293298-33-6 is helpful to your research.

Energetically significant nitrile center dot center dot center dot nitrile and unconventional C-H center dot center dot center dot pi(nitrile) interactions in pyridine based Ni(II) and Zn(II) coordination compounds: Antiproliferative evaluation and theoretical studies

Two new coordination compounds viz. [Ni(2,6-PDC)(Hdmpz)(H2O)(2)]center dot H2O (1) and [Zn(3-CNpy)(2)Cl-2] (2) (2,6-PDC = 2,6-pyridinedicarboxylate, Hdmpz = 3,5-dimethylpyrazole, 3-CNpy = 3-cyanopyridine) have been synthesized and characterized using elemental analysis, thermogravimetric analysis, electronic, infrared spectroscopy and single crystal X-ray diffraction techniques. Crystal structure analyses reveal the presence of supramolecular assemblies involving interesting dimers with unconventional contacts in the compounds. DFT (Density Functional Theory) calculations on the supramolecular dimers in the crystal structure of 1 reveal that the sum of contributions of anion-pi, pi-pi and other long range interactions due to the approximation of the bulk monomers is energetically significant. Molecular Electrostatic Potential (MEP) surface and Quantum Theory of Atoms in Molecules (QTAIM) analyses on the interesting supramolecular dimers of the crystal structures of 2 reveal the presence of unconventional anion center dot center dot center dot pi contacts involving coordinated chlorido ligands and C-H center dot center dot center dot pi(nitrile) interactions involving the pi-system of the nitrile moiety of 3-cyanopyridine. Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%). It is interesting that compound 1has excellent cytotoxic potency with IC50 closer to cisplatin and can bind different biological targets with similar signalling pathways. Structure activity relationship (SAR) analyses of 1 and 2 based on pharmacophore modelling reveal that the molecular features associated with the structures of the compounds play important role in the biological activities.
