5-Acetoxy-1-acetyl-3-pyrrolin-2-one

The chiral title compound, C8H9NO4, crystallizes in the non-centrosymmetric space group P2(1)2(1)2(1), but in the absence of an atom with significant anomalous dispersion, the absolute configuration could not be determined. The H atoms in both methyl groups are eclipsed with respect to the C=O bond. The structure features weak C-H center dot center dot center dot O interactions that link the molecules into a three-dimensional network.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 611-64-3. Application In Synthesis of 9-Methylacridine.

Switchable Synthesis of Pyrroles and Pyrazines via Rh(II)-Catalyzed Reaction of 1,2,3-Triazoles with Isoxazoles: Experimental and DFT Evidence for the 1,4-Diazahexatriene Intermediate

4-Aminopyrrole-3-carboxylates and pyrazine-2-carboxylates were synthesized from 5-alkoxyisoxazoles and 1-sulfonyl-1,2,3-triazoles by tuning the Rh(II) catalyst and the reaction conditions. The reaction in chloroform at 100 degrees C under Rh-2(OAc)(4) catalysis provides 4-aminopyrrole-3-carboxylates in good yields. The use of Rh-2(Piv)(4) in refluxing toluene results in the formation of 1,2-dihydropyrazine-2-carboxylates as the main products, which can be converted by a one-pot procedure to pyrazine-2-carboxylates by heating with catalytic amounts of TsOH. According to the NMR and DFT investigations of the reaction mechanism, pyrroles and dihydropyrazines are formed, respectively, via 1,5- and 1,6-cyclization of common (5Z)-1,4-diazahexa-1,3,5-triene intermediates. The influence of the nature of the catalyst on the product distribution is rationalized in terms of the Rh-catalyzed isomerization of a pyrrolin-2-ylium-3-aminide zwitterion, the primary product of 1,4-diazahexatriene 1,5-cyclization.

Practical Synthesis of alpha-Trifluoromethylated Pyridines Based on Regioselective Cobalt-Catalyzed [2+2+2] Cycloaddition using Trifluoromethylated Diynes with Nitriles

Regioselective cobalt-catalyzed [2+2+2] cycloaddition using fluorine-containing diynes with nitriles was described. Cycloaddition of fluorinated diynes with nitriles under the influence of CoCl2(phen), zinc bromide, and zinc dust in dichloroethane at 80 degrees C for 3 h took place smoothly, exclusively affording the corresponding alpha-fluoroalkylated pyridines in excellent yields. In addition, dinitriles as substrate were also found to be suitable for this reaction, giving the corresponding fluoroalkylated bipyridine derivatives in excellent yields.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 95-45-4, in my other articles.

Transfected adenosine A(1) receptor-mediated modulation of thrombin-stimulated phospholipase C and phospholipase A(2) activity in CHO cells

Thrombin receptor activation in Chinese hamster ovary (CHO) cells stimulates the hydrolysis of inositol phospholipids and the release of arachidonic acid. Our previous studies have shown that activation of the human transfected adenosine A(1) receptor in CHO cells (CHO-A1) potentiates the accumulation of inositol phosphates elicited by endogenous P-2U purinoceptors and CCKA receptors. In this study we have investigated whether adenosine A(1) receptor activation can modulate thrombin-stimulated arachidonic acid release and/or inositol phospholipid hydrolysis in CHO-A1 cells. Thrombin stimulated [H-3]arachidonic acid release and total [H-3]inositol phosphate accumulation in CHO-A1 cells. Both these responses to thrombin were insensitive to pertussis toxin. The protein kinase C activator, phorphbol 12-myristate 13-acetate (PMA), potentiated thrombin-stimulated [H-3]arachidonic acid. In marked contrast, PMA inhibited thrombin-stimulated [H-3]inositol phosphate accumulation. The selective protein kinase C inhibitor Ro 31-8220 (3-{1-[3-(2-isothioureido)propyl]indol-3-yl}-4-(1-methylindol-3-yl)-3-pyrrolin-2,5-dione) had no effect on thrombin-stimulated [H-3]arachidonic acid release but reversed the potentiation of thrombin-stimulated [H-3]arachidonic acid release elicited by PMA. The selective adenosine A(1) receptor agonist N-6-cyclopentyladenosine (CPA) augmented the release of [H-3]arachidonic acid produced by thrombin. Co-activation of the adenosine A(1) receptor also potentiated thrombin-stimulated [H-3]inositol phosphate accumulation. The synergistic interactions between the adenosine A(1) receptor and thrombin were abolished in pertussis-toxin-treated cells. The potentiation of [H-3]arachidonic acid release by CPA was blocked by the protein kinase C inhibitors Ro 31-8220 and GF 109203X (3-[1-[3-(dimethylamino)propyl]-1H-indol-3-yl]-4-(1H-indol-3-yl)-1H-pyrrole-2,5-dione). In conclusion, thrombin receptor activation in CHO-A1 cells stimulates the accumulation of [H-3]inositol phosphates and the release of [H-3]arachidonic acid through pertussis-toxin-insensitive G-proteins. Experiments using PMA suggest that protein kinase C differentially regulates thrombin receptor activation of phospholipase C and phospholipase A(2). Co-activation of the transfected human adenosine A(1) receptor augments thrombin-stimulated phospholipase C and phospholipase A(2) activity. Finally, the augmentation of phospholipase A(2) activity by the adenosine A(1) receptor is inhibited by selective protein kinase C inhibitors, suggesting the involvement of protein kinase C.

Synthesis of spin-labeled RNAs for long range distance measurements by PELDOR

Site directed spin labeled RNA duplexes with different interspin distances were synthesized. The radical 2,2,5,5-tetramethyl-pyrrolin-1-yloxyl-3-acetylene (TPA) was introduced during the solid-phase synthesis through a Sonogashira cross-coupling with 5-iodo-uridine. T-m and CD studies showed that the spin label does not to disturb significantly the A-form of these duplexes. 4-Pulse Electron Double Resonance (PELDOR) was then used to measure intramolecular spin-spin distances of 19.3, 33.0 and 40.9 angstrom, which are in very good agreement with the calculated values of 17 6 32.1 and 39.1 angstrom, obtained from Molecular Dynamics (MD) simulations.

New applications of N-acyliminium precursors: Tetracarbonyliron-mediated stereoselective alkylations of 5-(R)-isopropoxy-3-pyrrolin-2-ones

Lewis acid catalyzed allylic substitutions with several nucleophiles at C-5 of the cis-tetracarbonyliron complexes of N-acetyl- and N-tosyl-5-(R) -isopropoxy-3-pyrrolin-2-ones occur highly regio- and stereoselectively. The results are interpreted as being indicative of the intermediacy of a ( pi-allyl)tetracarbonyliron cation, with possible preceding formation of an N-acyl- or an N-tosyliminium ion.
