The development of a novel protocol for the fast introduction of the picolinamide directing group in aliphatic ketones by using the ammonia-Ugi 4-CR reaction and the subsequent evaluation of the Pd-mediated gamma-C(sp3)-H bond activation is described. The methodology allows the efficient construction of a series of gamma-arylated alpha-aminoamides bearing a congested carbon in two steps.

Chemistry is traditionally divided into organic and inorganic chemistry. Application In Synthesis of 1-Chloroisoquinoline, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 19493-44-8

A new phosphorescent (CQ-BP)2Ir(acac), (CMQ-BP)2Ir(acac), (BQ-BP)2Ir(acac) was synthesized for organic light-emitting diodes (OLEDs). OLEDs using phosphorescent iridium(III) complexes attract enormous attention because they allow highly efficient electro phosphorescence. The donor-acceptor type ligands for the Iridium(III) complexes were synthesized by Suzuki coupling reaction. The ligands through changes in oxidative addition materials (electron-acceptor) and organic borane (electron-donor) to get the red color were to study the appropriate Iridium(III) complexes. Oxidative addition materials were used such as 2-chloro-4-methylquinoline, 1-chloroisoquinoline and 2-bromoquinoline. 4-tert-Butylphenyl-boronic acid was used as organic borane. The dopant was synthesized by Nonoyama reaction. Red dopants were observed with an emission peak at approximately 600 nm. Iridium(III) complexes were measured by nuclear magnetic resonance (NMR), UV-visible spectroscopy and photoluminescence (PL). The phosphorescence emission maxima were dependent on the electron density of donor and acceptor moiety of the ligands.

Pyridine N-oxide-BF2CF3 and-BF2C 2F5 complexes and their derivatives were synthesized. Most of the complexes show fluorescence both in solution and in the solid state. By expanding the pi-conjugated skeleton, the color of the fluorescence could be changed dramatically. A fluorophore with a high solvent dependency could also be produced. Since such compounds can be synthesized on a gram scale in high yield, and are stable to oxygen, water, and heat, the complexes hold great potential as organic functional materials. Too complex for simple answers: Complexes of pyridine N-oxide with BF2CF3 and BF 2C2F5, and their derivatives were synthesized. Most of the complexes fluoresce, both in solution and in the solid state. By expanding the pi-conjugated skeleton, the color of the fluorescence could be changed dramatically. Owing to their properties such complexes hold potential as organic functional materials.

A large proportion of medicinally relevant molecules bear nitrogen and sp3-hybridized carbon functionalities. Overwhelmingly, these atoms are found as part of (hetero)cyclic structures. Despite their importance, synthetic approaches to saturated nitrogen heterocycles are limited to several established stoichiometric alkylation techniques, as well as a few methods involving C-H bond activation. The synthetic community remains interested in more general, mild, and sustainable ways to access these motifs. Here we describe a dual-catalyst system composed of an iridium photocatalyst and a lithium phosphate base that is capable of selectively homolyzing the N-H bond of 4-alkyl-1,4-dihydropyridines, presumably by proton-coupled-electron-transfer (PCET), and mediating efficient cyclization of the resultant carbon-centered radicals with tethered imines. The outcome of this transformation is access to a broad range of structurally complex nitrogen heterocycles obtainable from simple aldehyde starting materials in a highly chemoselective manner.

The addition of the lithium carbanion of methyl phenyl sulfoxide and (R)-(+)-methyl p-tolyl sulfoxide to imines having at least one aryl substituent, under kinetically controlled conditions, gives beta-amino sulfoxides with good to modest diastereoselection.Under equilibrium controlled condition poor product diastereoselection results.The addition of these anions to 3,4-dihydro-6,7-dimethoxyisoquinoline is unique in that the most favorable product diastereoselection (92:8) is observed under equilibrium controlled conditions.Deuteration experiments suggest that equilibration occurs via a beta-amino alpha-lithio sulfinyl carbanion through a retro-Michael addition then Michael addition reaction sequence.This methodology allows for the construction of (R)-(+)-tetrahydropalmatine in four efficient synthetic steps.

Although quaternary ammonium and phosphonium salts are known as important catalysts in phase-transfer catalysis, the catalytic ability of tertiary sulfonium salts has not yet been well demonstrated. Herein, we demonstrate the catalytic ability of trialkylsulfonium salts as hydrogen-bonding catalysts on the basis of the characteristic properties of the acidic alpha hydrogen atoms on alkylsulfonium salts.

A facile, transition-metal-free, and direct decarboxylative arylation of 2-picolinic acids with simple arenes is described. The oxidative decarboxylative arylation of 2-picolinic acids with arenes proceeds readily via N-chloro carbene intermediates to afford 2-arylpyridines in satisfactory to good yields under transition-metal-free conditions. This new type of decarboxylative arylation is operationally simple and scalable and exhibits high functional-group tolerance. Various synthetically useful functional groups, such as halogen atoms, methoxycarbonyl, and nitro, remain intact during the decarboxylative arylation of 2-picolinic acids.

A single set of reaction conditions for the palladium-catalyzed amination of a wide variety of (hetero)aryl halides using primary alkyl amines has been developed. By combining the exceptionally high reactivity of the Pd-PEPPSI-IPentCl catalyst (PEPPSI=pyridine enhanced precatalyst preparation, stabilization, and initiation) with the soluble and nonaggressive sodium salt of BHT (BHT=2,6-di-tert-butyl-hydroxytoluene), both six- and five-membered (hetero)aryl halides undergo efficient and selective amination.

A large amount of stable ecteinascidin 770 (1b) was isolated from the Thai tunicate, Ecteinascidia thurstoni, which was pretreated with potassium cyanide in buffer solution (pH 7), along with a minor metabolite, ecteinascidin 786 (1c). A number of 6?-O-acyl derivatives 3-19 and three diacetyl derivatives 2a-c of the stable 1b were prepared and evaluated for activity against human tumor cell lines HCT116, QG56, and DU145. Nitrogen-containing heterocyclic ester derivatives such as 12, 13, and 16-19 showed similar in vitro cytotoxicity to 1b, whereas the other derivatives were less cytotoxic than 1b. Furthermore, we discovered that the N-indole-3-carbonyl derivative of ecteinascidin 770 (22) has higher cytotoxicity than 1b.
