Synthesis and Resolution of 1-(2-Diphenylphosphino-1-naphthyl)isoquinoline; a P-N Chelating Ligand for Asymmetric Catalysis

A multistep synthesis resulting in a good yield of the title compound has been developed based on the Pd-catalysed coupling of 1-chloroisoquinoline and 2-methoxy-1-naphthylboronic acid (5).The product is converted into the corresponding trifluoromethanesulphonate (10) by successive demethylation and treatment with (CF3CO)2O, followed by a further Pd-catalysed coupling with Ph2P(O)H.The resulting phosphine oxide (11) was cleanly reduced with HSiCl3.Resolution of the phosphinamine (4) was carried out with the Pd complex derived from (R)-(+)-dimethyl(1-(1-naphthyl)ethyl)amine and PdCl2; the diastereomers were of different stabilities and solubilities and were therefore readily separated.The resolved phosphinamine, D22 +/- 153 (c = 1, CHCl3), was enantiomerically stable on heating to 65 deg C for 24h.X-ray crystal structures of the adduct (16) and the Pd dimer (7) isolated during the initial coupling reaction are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C9H7NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1532-72-5, in my other articles.

External-Photocatalyst-Free Visible-Light-Mediated Synthesis of Indolizines

A visible-light-mediated synthesis of valuable polycyclic indolizine heterocycles from easily accessed brominated pyridine and enol carbamate derivatives has been developed. This process, which operates at room temperature under irradiation from readily available light sources, does not require the addition of an external photocatalyst. Instead, an investigation into the reaction mechanism indicates that the indolizine products themselves may be in some way involved in mediating and accelerating their own formation. Preliminary studies also show that these simple heterocyclic compounds may be capable of facilitating other visible-light-mediated transformations.

Transition-metal- and oxidant-free three-component reaction of quinoline: N -oxides, sodium metabisulfite and aryldiazonium tetrafluoroborates via a dual radical coupling process

A convenient and straightforward three-component transformation of quinoline N-oxides, sodium metabisulfite and aryldiazonium tetrafluoroborates has been developed, providing the target products in moderate to good yields. Compared with previous studies, the present methodology avoids the use of transition-metal catalysts and excess oxidants, providing a simple and practical alternative approach for the construction of 2-sulfonylquinolines. Control experiments indicate that a dual radical coupling process is responsible for this reaction.

Organoselenium-Catalyzed Aza-Wacker Reactions: Efficient Access to Isoquinolinium Imides and an Isoquinoline N -Oxide

An efficient approach for the organoselenium-catalyzed aza-Wacker reaction of olefinic hydrazones and an oxime to form isoquinolinium imides and an isoquinoline N -oxide is developed. This transformation involves a direct intramolecular C-H amination using hydrazones and an oxime as imine-type nitrogen sources. This work not only provides a new approach for the construction of isoquinoline derivatives, but also expands the scope of nitrogen sources in electrophilic selenium catalysis.

TsCl-promoted sulfonylation of quinoline N-oxides with sodium sulfinates in water

An eco-friendly protocol for the synthesis of various 2-sulfonyl quinolines/pyridines through sulfonylation of heteroaromatic N-oxides with sodium sulfinates in water at ambient temperature under metal- and oxidant-free conditions has been developed. The mild reaction conditions, high reaction efficiency, operational simplicity, short reaction time and remarkable functional-group compatibility make the developed protocol very attractive for the preparation of 2-sulfonyl N-heteroaromatic compounds.

Eradication of Helicobacter pylori through the inhibition of urease and peptide deformylase: Computational and biological studies

This work tested anti- Helicobacter pylori, free radicals scavenging and toxicity property as well as chemical constituents in the extract of chloroform (CE) and ethyl acetate (EAE) from the pedicel of Diospyros kaki L. (PDK-CE and PDK-EAE). There were 33 and 36 chemical constituents respectively in the extracts of PDK-CE and PDK-EAE, belonging to the fatty acids methyl ester, fatty acids, and stearic acids, as revealed by Gas Chromatography-Mass Spectrometry (GC-MS). The extracts did not exhibit any toxicity on NIH3T3 cells, but they significantly showed scavenging of NO, DPPH, and H2O2 free radicals. The extracts displayed in vitro anti-H. pylori activity. PDK-CE had the maximum inhibitory zone at a minimal inhibitory concentration (MIC) of 10 mug. ml?1 and the extract also triggered the cellular damage in the bacteria. PDK-CE extract had a high urease inhibitory activity (IC50 value of 8.5 mug). Further, in silico studies was performed by using 41 compounds against H. pylori urease (HPU) and H. pylori peptide deformylase (HPPD). The score value was the maximum (?19.58 kcal/mol) against HPU with 17-(5-ethyl-6-methylheptan-2-yl)-10,13-dimethyl-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-ol, while the score value was the maximum (?14.51 kcal/mol) against HPPD with hexadecanoic acid. The results demonstrated the importance of the pedicel extracts in future pharmaceutical drug development against H. pylori infections.

An Improved Rapid and Mild Deoxygenation of Amine N-oxides

An improved mild and selective method for the deoxygenation of a variety of amine N-oxides has been carried out in the presence of silica gel under mild conditions at room temperature to afford corresponding amines in relatively good yields without purification. The reaction is tolerant of a variety of functional groups such as hydroxyl, ester, acid, carbonyl, and cyano groups, as well as halogens. This method would be of great utility to synthesize various pyridines and amines easily.

Hypervalent Iodine(III)-Mediated Regioselective Cyanation of Quinoline N-Oxides with Trimethylsilyl Cyanide

A regioselective cyanation of quinoline N-oxides with trimethylsilyl cyanide was developed by using (Diacetoxyiodo) benzene (PIDA) as mediated hypervalent iodine(III) reagent under metal-free and base-free reaction conditions to obtain 2-cyanoquinolines. The efficient PIDA reagent could play the role of an activator of the substrates and an accelerator of N?O bond cleavage. The reaction system featured a wide range of substrate suitability and high yields. The procedure was enlarged gram-scale to synthesize the tuberculosis (TB) inhibitor. Finally, according to some experimental results, a plausible mechanism for the cyanation reaction is proposed. (Figure presented.).
