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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 163931-61-1, you can contact me at any time and look forward to more communication. COA of Formula: https://www.ambeed.com/products/163931-61-1.html.

New synthesis of highly functionalized 3-pyrrolin-2-ones

Ethyl N-aryl-(or N-alkyl)-oxamate undergo a smooth reaction with triphenylphosphine and dirnethyl acetylenedicarboxylate to produce dimethyl N-aryl-(or N-alkyl)-3-ethoxy-3-pyrrolin-2-one-4,5-dicarboxylates in fairly high yields.

Synthesis and Transformation of Triterpenoids with a beta-Ketonitrile Fragment in Five-Membered Ring A

Triterpenoids with a beta-ketonitrile group in five-membered ring A were synthesized via intramolecular oxonitrile cyclization of C-3 methyl esters of 1-cyano-substituted 2,3-seco-triterpene acids. The intramolecular cyclization to form the triterpene ketonitriles and subsequent reduction of the oxo groups to give C-1 and C-3 substituents in the beta-orientation were confirmed to be stereoselective. Alkaline hydrolysis of the ketonitriles reduced the cyano groups to form the corresponding 3-oxo-2-nor-derivative while reduction and acylation of the beta-hydroxynitrile formed an alpha,beta-alkenenitrile fragment in the triterpenoid five-membered ring A.

N-Benzyloxymalimide for an easy access to 5-alkyl-3-pyrrolin-2-ones: asymmetric synthesis of the mixed imide substructure of the potent immunosuppressant microcolin B

O-Benzyl-N-benzyloxymalimide 12 has been synthesized as a useful variant of the chiral building blocks 9. The advantage of the malimide 12 over 9 was demonstrated by mild and high-yielding reductive N-deprotection of N-benzyloxylactams 18a-i to give a series of (4R,5S)-5-alkyl-4-hydroxy-pyrrolidin-2-ones, which are key intermediates for the asymmetric synthesis of pyrrolidines, pyrrolizidines, and indolizidines, as well as beta-hydroxy gamma-amino acids. Lactam ent-11a has been applied to the synthesis of the mixed imide 25, a key intermediate for the total synthesis of microcolin B, which also demonstrated that lactam ent-11a or 11a can serve as a latent form of the 5-methyl-3-pyrrolin-2-one substructure of majusculamide D 4, deoxymajusculamide D, and the jamaicamides A-C.

Synthesis of Illudinine from Dimedone and Identification of Activity as a Monoamine Oxidase Inhibitor

The fungal metabolite illudinine is prepared in seven steps and ca. 55% overall yield from dimedone using an open and shut (ring-opening and ring-closing) strategy. Tandem ring-opening fragmentation and olefination of dimedone establishes alkyne and vinylarene functionality linked by a neopentylene tether. Oxidative cycloisomerization then provides the illudinine framework. The key innovation in this second-generation synthesis of illudinine is the use of the nitrile functional group, rather than an ester, as the functional precursor to the carboxylic acid of illudinine. The small, linear nitrile (C N) is associated with improved selectivity, pi-conjugation, and reactivity at multiple points in the synthetic sequence relative to the carboxylic acid ester. Preliminary assays indicate that illudinine and several related synthetic analogues are monoamine oxidase inhibitors, which is the first reported indication of biological activity associated with this natural product. Illudinine was found to inhibit monoamine oxidase B (MAO-B) with an IC50 of 18 +/- 7.1 mu M in preliminary assays.

ACYLATION OF ALDO 1-PYRROLINE 1-OXIDES (4,5-DIHYDRO-3H-PYRROLE 1-OXIDES) AND THE OXIDATION OF THE RESULTING 3-ACYLOXY-1-PYRROLINES (3-ACYLOXY-4,5-DIHYDRO-3H-PYRROLES)

5,5-Dimethyl-1-pyrroline 1-oxide (DMPO), when treated with NaH (1 mol) followed by ethyl chloroformate, benzoyl chloride, pivaloyl chloride or 2-bromoisobutyryl bromide gave the corresponding 3-acyloxy-1-pyrrolines. With NaH (2-4 mel) followed by benzoyl chloride or 2-bromoisobutyryl bromide, DMPO gave the corresponding 2-(3′-acyloxy-1′-pyrrolin-3′-yl)-3-acyloxypyrrolidines. Acylation of the 3-phenyl and 3-methyl DMPOs also gave the corresponding 3-acyloxy-1-pyrrolines. Oxidation of the 3-acyloxy-1-pyrrolines with m-CPBA gave the corresponding oxaziridines in good yield. These oxaziridines were resistant to ring opening by acid hydrolysis, photolysis and thermolysis.

Divergent Synthesis of Multisubstituted Unsymmetric Pyrroles and Pyrrolin-4-ones from Enamino Esters via Copper-Catalyzed Aerobic Dimerization

A facile synthetic method to access multisubstituted unsymmetric pyrrole and pyrrolin-4-one derivatives is disclosed. In the presence of Cu(OAc)(2) and KOAc, substituted pyrrole derivatives are produced in good yields (up to 93 %) through oxidative cyclization of enamino esters. Meanwhile, using CuCl2 and TFA (trifluoroacetic acid), pyrrolin-4-one derivatives are obtained in excellent yields (up to 94 %) through 1,2-aryl migration. A wide range of functional groups have been tolerated, and a reliable method for the synthesis of valuable multisubstituted pyrroles and pyrrolin-4-ones has been developed.

Azide Radical Initiated Ring Opening of Cyclopropenes Leading to Alkenyl Nitriles and Polycyclic Aromatic Compounds

We report herein a radical-mediated amination of cyclopropenes. The transformation proceeds through a cleavage of the three-membered ring after the addition of an azide radical on the strained double bond and leads to tetrasubstituted alkenyl nitrile derivatives upon loss of N-2. With 1,2-diaryl substituted cyclopropenes, this methodology could be extended to a one-pot synthesis of highly functionalized polycyclic aromatic compounds (PACs). This transformation allows the synthesis of nitrile-substituted alkenes and aromatic compounds from rapidly accessed cyclopropenes using only commercially available reagents.

Spectroscopic calculations, Hirshfeld surface analysis, and molecular docking studies of anticancer 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile

The title compound 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile was deliberated by proton nuclear magnetic resonance, ultraviolet-visible, and Fourier transform infrared spectroscopy techniques. The theoretical optimized geometrical parameters (bond lengths, bond angles and dihedral angles), vibrational wavenumbers, and the non-linear optical properties were calculated using the density functional theory with the Becke, 3-parameter, Lee-Yang-Parr functional method. Hirshfeld surface and two-dimensional fingerprint plot analyses have been performed to study the nature of intermolecular interactions within the crystal structure. The ultraviolet-visible spectrum, global chemical reactivity descriptors, the highest occupied molecular orbital and the lowest unoccupied molecular orbital energies in acetonitrile solvent have performed by Time-Dependent Density Functional Theory approach. The molecular electrostatic potential used to predict the reactive sites indicates that the nitrogen atom of the nitrile group is prone to electrophilic attack, and the hydrogen atoms belonging to the amino group to nucleophilic attack. The first-order hyperpolarizability value indicates that the title compound is a useful claimant as non-linear optical material studies. The reduced density gradient function based on electron density provides a simple, clear, and practical method to research non-covalent interactions was investigated. Molecular docking studies of the title compound have been performed, which suggests that the title molecule may act as a potential anticancer agent.
