NaBH4-TMEDA and a palladium catalyst as efficient regio- and chemoselective system for the hydrodehalogenation of halogenated heterocycles

The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.

Visible-Light-Induced Pyridylation of Remote C(sp3)?H Bonds by Radical Translocation of N-Alkoxypyridinium Salts

Metal-free, visible-light-induced site-selective heteroarylation of remote C(sp3)?H bonds has been accomplished through the design of N-alkoxyheteroarenium salts serving as both alkoxy radical precursors and heteroaryl sources. The transient alkoxy radical can be generated by the single-electron reduction of an N-alkoxypyridinium substrate by a photoexcited quinolinone catalyst. Subsequent radical translocation of the alkoxy radical forms a nucleophilic alkyl radical intermediate, which undergoes addition to the substrate to achieve remote C(sp3)?H heteroarylation. This cascade strategy provides a powerful platform for remote C(sp3)?H heteroarylation in a controllable and selective manner and is well suited for late-stage functionalization of complex bioactive molecules.

Metal-Free Direct C?H beta-Carbonyl Alkylation of Heteroarenes with Cyclopropanols Mediated by K2S2O8

Direct C?H beta-carbonyl alkylation of heteroarenes under metal-, acid- and photo-catalyst free conditions has been achieved. A wide scope of substrates, such as various substituted quinolines and isoquinolines, pyridines, pyridazine, benzo[d]thiazole and phenanthroline, underwent the beta-carbonyl alkylation efficiently via K2S2O8-mediated ring-opening of cyclopropanols. The corresponding beta-heteroarylated ketones were obtained in moderate to excellent yields and gram-scale experiments further demonstrated the practicality of this synthetic protocol. The readily available reagents, mild and environmentally benign conditions make the method extremely attractive. The reaction mechanism is also proposed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 3-Methylisoquinoline, you can also check out more blogs about1125-80-0

Synthesis of Pterocarpan Derivatives and their Inhibitory Effects against Microbial Growth and Biofilms

Pterocarpans are rare isoflavone derivatives that occur in limited Fabaceous plants. The Heck oxyarylation of 2H-chromenes with o-iodophenols offered access to several naturally occurring pterocarpans. Among them, medicarpin showed antifungal activity to Fusarium; however, these compounds were nearly water-insoluble. To overcome this drawback, azamedicarpin HCl salt as a medicarpin mimic was designed and prepared via the Heck azaarylation. Effects of the salt against growth and biofilms of clinically relevant bacteria and fungi were studied. Our findings exemplified that azapterocarpan HCl salt may be beneficial as a potentiated water-soluble form and valuable for biofilm-related Candida infections.

Resolution and coupling of 1-(2?-hydroxy-1?-naphthyl)isoquinolines

The synthesis of bridged dimeric isoquinolylnaphthols has been developed. A simple method for the resolution of 1,1?-isoquinolyl-2?-naphthol permits measurement of the optical stability of the monomer, and in several cases slow racemisation at ambient temperature was observed. The enantiomeric stability is not greatly affected by steric buttressing. An unusual enhancement of the rate of atropisomerism is provided by the 3-bromomethylisoquinolines, and undermines the possibility of coupling pure enantiomeric components to provide a single stereoisomer of a tetradentate ligand.

Novel dehydroabietylamine derivatives as potent inhibitors of acetylcholinesterase

Nowadays, the inhibition of acetylcholinesterase is one of the main pharmacological strategies for the treatment of Alzheimer’s disease. Therefore, a set of thirty-four derivatives of the diterpenoid dehydroabietylamine has been synthesized and screened in colorimetric Ellman’s assays to determine their ability to inhibit the enzymes acetylcholinesterase (AChE, from electric eel) and butyrylcholinesterase (BChE, from equine serum). A systematic variation of the substitution of dehydroabietylamides enabled an approach to analogs showing a remarkable inhibition potency for AChE. Particularly N-benzoyldehydroabietylamines 11, 12 and 13 were excellent inhibitors for AChE, showing inhibition rates comparable to standard galantamine hydrobromide.

Hyperbranched polymers with aggregation-induced emission property for solution-processed white organic light-emitting diodes

In this work, a new series of hyperbranched polymers of PFTPE-Ir(piq)3-X(X = 1, 5, 10) were designed and synthesized, in which tris(1-phenylisoquinoline)iridium(?) (Ir(piq)3) acts as red emission core and PFTPE acts as branches. The photophysical study reveals that these hyperbranched polymers exhibit aggregation-induced emission (AIE) characteristic, inducing in much higher photoluminescent quantum yield (PhiY) in neat film than that in dilute tetrahydrofuran (THF) solution. The white-light OLEDs using PFTPE-Ir(piq)3-X as emission layer show rather weaker efficiency roll-off. Especially, the white-light OLED based on PFTPE-Ir(piq)3-5 as emission layer shows a maximum luminance of 4686 cd/m2, a maximum luminous efficiency of 2.43 cd/A, a maximum external quantum efficiency of 1.08% and the Commission Internationale de l’Eclairage coordinate of (0.26, 0.36).

Iron-Catalyzed Isopropylation of Electron-Deficient Aryl and Heteroaryl Chlorides

Traditional methods for the preparation of secondary alkyl-substituted aryl and heteroaryl chlorides challenge both selectivity and functional group tolerance. This contribution describes the use of statistical design of experiments to develop an effective procedure for the preparation of isopropyl-substituted (hetero)arenes with minimal isopropyl to n-propyl isomerization. The reaction tolerates electronically diverse aryl chloride coupling partners, with excellent conversion observed for strongly electron-deficient aromatic rings, such as esters and amides. Electron-rich systems, including methyl- and methoxy-substituted aryl chlorides, were found to be less reactive. Furthermore, the reaction was found to be most successful when heteroaryl chlorides were submitted to the cross-coupling protocol. By mapping substituent effects on reaction selectivity, we were able to show that electron-deficient aryl chlorides are essential for efficient coupling, and use electronic structure calculations to predict the likelihood of successful coupling through the estimation of the electron affinity of each aryl chloride. Moderate isolated yields were achieved with selected aryl chlorides, and moderate to good isolated yields were obtained for all the heteroaryl chlorides coupled. Excellent selectivity was observed when a 2,6-dichloroquinoline was used, allowing mono-substitution on a challenging substrate. (Figure presented.).

Exploitation of differential reactivity of the carbon-chlorine bonds in 1,3-dichloroisoquinoline. Routes to new N,N-chelate ligands and 1,3-disubstituted isoquinolines

Under Pd(PPh3)4 catalysis, coupling of arylboronic acids to the 1-position of 1,3-dichloroisoquinoline takes place, leading exclusively to 1-aryl-3-chloroisoquinolines. This regiochemistry is demonstrated by the crystal structure of 3-chloro-1-(8-methoxy-1-naphthyl)isoquinoline. The 3-chloro group may be modified by nickel-catalysed reaction with Grignard reagents or direct nucleophilic displacement with LiSCH2Ph. Attempted lithiation of the 3-position is not successful (either deprotonation or complex reactivity results). Under zinc reduction in the presence of NiCl2-PPh3 and NaI, the 1-aryl-3-chloroisoquinolines furnish 3,3?-biisoquinolines in good yield.
