Synthesis of functionalized 3-, 5-, 6-and 8-aminoquinolines via intermediate (3-pyrrolin-1-yl)- and (2-oxopyrrolidin-1-yl)quinolines and evaluation of their antiplasmodial and antifungal activity

(3-Pyrrolin-1-yl)- and (2-oxopyrrolidin-1-yl)quinolines were prepared via cyclization of diallylaminoquinolines and 4-chloro-N-quinolinylbutanamides, respectively, as novel synthetic intermediates en route to N-functionalized 3-, 5-, 6- and 8-aminoquinolines with potential biological activity. (3-Pyrrolin-1-yl)quinolines were subjected to bromination reactions, and the reactivity of (2-oxopyrrolidin-1-yl)quinolines toward lithium aluminum hydride and methyllithium was assessed, providing an entry into a broad range of novel functionalized (pyrrolidin-1-yl)- and (hydroxyalkylamino) quinolines. Antiplasmodial evaluation of these novel quinolines and their functionalized derivatives revealed moderate micromolar potency against a chloroquine-sensitive strain of the malaria parasite Plasmodium falciparum, and the two most potent compounds also showed micromolar activity against a chloroquine-resistant strain of P. falciparum. Antifungal assessment of (hydroxyalkylamino)quinolines revealed three compounds with promising MIC values against Rhodotorula bogoriensis and one compound with potent activity against Aspergillus flavus.

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.

On the methylacetylene abundance and nitrogen isotope ratio in Pluto’s atmosphere

To bring our photochemical model of Pluto’s atmosphere and ionosphere (Krasnopolsky, 2020) into agreement with the recent detection of 5 x 10(15) cm(-2) methylacetylene C3H4 (Steffl et al., 2020), rate coefficients of the three key reactions of C3H4 production and loss have been changed to values calculated by (2019). This change reduces the abundance of cyanoacetylene HC3N close to the measured ALMA upper limit (Lellouch et al., 2017), increases the model abundances of H-2 and C3H8 by factors of 1.3, and reduces the abundances of H and C4H2 by factors of 1.3, while other species are changed less than 5% in the model. The predicted abundance of atomic hydrogen agrees with that derived from the observed Lyman-beta emission by Steffl et al. (2020). The observed (HCN)-N-14/(HCN)-N-15 > 125 on Pluto (Lellouch et al., 2017) looks puzzling compared to (HCN)-N-14/(HCN)-N-15 = 60 on Titan. Our analysis confirms the predissociation of N 2 at 80-100 nm as the main process of nitrogen isotope fractionation. The observed twofold difference is partially caused by the diffusive depletion of the heavy isotope in HCN and in the predissociation of N-2. On Pluto, the mean altitudes of HCN and predissociation of N-2 are 500 and 860 km, well above the homopause at 96 km. On Titan, observations of (HCN)-N-14/(HCN)-N-15 refer to 90-460 km (Vinatier et al., 2007), the predissociation occurs near 985 km, both below the homopause at 1000 km, and diffusive depletion does not occur. Therefore the observed limit corresponds to N-14/(15) N > 253 for N-2 in the lower atmosphere and N-14/N-15 > 228 in the upper layers of the N-2 ice. These limits reflect the conditions on Pluto in the last two million years, which is the lifetime of N-2 in Pluto’s atmosphere with the current N-2 loss of 37.5 g cm(-2) Byr(-1) primarily for photodestruction. The calculated isotope fractionation factor of 1.96 accounts for the formation and condensation of nitriles, diffusive separation, and fractionation in thermal escape. Variations of N-14/N-15 in the N-2 ice are related to the evolution of the solar EUV, mixing processes in the N-2 ice, and possible periods of hydrodynamic escape, which are poorly known and not considered here.

Nitriles as radical acceptors in radical cascade reactions

The cyano group is a valuable and readily available functional group for the preparation of various functional groups, such as amines, carboxylic acids, and ketones. In recent decades, the radical cascade reaction has emerged as a versatile tool to prepare a large variety of functional molecules. The application of the cyano group as a radical acceptor in cascade reactions provides diverse opportunities for the convenient construction of various important heterocycles and carbocycles. Such synthetic strategies will open new ways for the rapid buildup of molecular complexity. The focus of this review is the summary of the dynamic field of radical cascade processes using the cyano group as a radical acceptor, which has not been well documented so far.

Raman and Surface Enhanced Raman Spectroscopy of 2,2,5,5-Tetramethyl-3-pyrrolin-1-yloxy-3-carboxamide Labeled Proteins: Bovine Serum Albumin and Cytochrome c

2,2,5,5-Tetramethyl-3-pyrrolin-1-yloxy-3-carboxamide (tempyo) labeled bovine serum albumin and cytochrome c at different pH values were prepared and investigated using Raman-resonance Raman (RR) spectroscopy and surface enhanced Raman scattering (SERS) spectroscopy. The Raman spectra of tempyo labeled proteins in the pH 6.7-11 range were compared to those of the corresponding free species. The SERS spectra were interpreted in terms of the structural changes of the tempyo labeled proteins adsorbed on the silver colloidal surface. The tempyo, spin label was found to be inactive in the Raman-RR and SERS spectra of the proteins. The a-helix conformation was concluded to be more favorable as the SERS binding site of bovine serum albumin. In the cytochrome c the enhancement of the bands assigned to the porphyrin macrocycle stretching mode allowed the supposition of the N-adsorption onto the colloidal surface.

Exploring Coumarins Reduction: NaBH4/MeOH versus Nickel Boride Generated In Situ.

The role of reagents NaBH4/MeOH and nickel boride (Ni2B) generated in situ from NaBH4 and NiCl2, are compared in the reduction process of coumarin and a variety of 3,7-substituted coumarins bearing electro-donating (ED-group) or electro-withdrawing groups (EW-group). Coumarins (chromen-2-one) are only reduced with Ni2B to the cyclic chromanones. This provides a useful and very simple reduction method for electron-rich coumarins, which are resistant to many other reducing methods. DFT calculations underlined the role of substituents electronic effects in the reactivity. Subsequent methanolysis may open the ring to methyl phenylpropanoate esters and alcohols resulting from their reductions can also be produced.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 163931-61-1, you can contact me at any time and look forward to more communication. Safety of Tetrabutylammonium difluorotriphenylsilicate(IV).

Studies on the pyrrolinone metabolites derived from the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine)

Previous studies have established that the tobacco alkaloid 1-methyl-2-(3-pyridyl)pyrrole (beta-nicotyrine) is biotransformed by rabbit lung and liver microsomal preparations to an equilibrium mixture of the corresponding 3- and 4-pyrrolin-2-ones. Autoxidation of these pyrrolin-2-ones generates the chemically stable 5-hydroxy-5-(3-pyridinyl)-3-pyrrolin-2-one. This paper summarizes efforts to document more completely the pathway leading to this hydroxy-pyrrolinone. Chemical and spectroscopic evidence implicates the 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole (2-hydroxy-beta-nicotyrine) as the key intermediate in this reaction pathway. Of potential toxicological interest is the detection of radical species derived from the autoxidation of this compound.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 611-64-3. Recommanded Product: 611-64-3.
