Cu2O/1-(2-methylhydrazine-1-carbonyl)-isoquinoline 2-oxide catalyzed C-N cross-coupling reaction in aqueous media

An experimentally simple, efficient, and inexpensive catalyst system was developed for the N-arylation of imidazole, indole, pyrrole, alkyl alcohol amines, and alkyl amines with aryl iodides and bromides. The reaction proceeds in water-ethanol media at 120 C for 12 h with Cu2O as the catalyst, 1-(2-methylhydrazine-1-carbonyl)-isoquinoline 2-oxide (L2) as the ligand, NaOH as the base to generate a wide range of N-arylated products in moderate to excellent yields. Aqueous medium, ease of operation, and broad substrate scope give the process a benign environmental profile.

Palladium-Catalyzed Mono-alpha-arylation of Acetone at Room Temperature

The first examples of acetone mono-alpha-arylation at room temperature are described, enabled by use of a [Pd(cinnamyl)Cl]2/JosiPhos catalyst system. (Hetero)aryl chloride, bromide, and iodide electrophiles featuring or lacking ortho-substitution, and comprising a range of functionalities (e.g., alkoxy, cyano, fluoro, trifluoromethyl, or alkenyl) and heteroaryl motifs (e.g., pyrrole, pyridine, isoquinoline, quinoline, quinaldine, (benzo)thiophene, benzothiazole, or benzodioxole) were successfully accommodated. Proof-of-principle experiments confirm that other (hetero)aryl methyl ketones can also be employed in such room temperature mono-alpha-arylations. The established substrate scope is the most extensive reported to date for acetone mono-alpha-arylation under any conditions, and more generally represents the first room temperature ketone mono-alpha-arylations employing a structurally diverse set of (hetero)aryl chlorides.

Highly selective tripeptide thrombin inhibitors

Tripeptide aldehydes such as Boc-D-Phe-Pro-Arg-H (5l) exhibit potent direct inhibition of thrombin. This distinction offers important insight for the design of more potent and selective serine protease inhibitors which may be useful pharmacological tools and hold promise for development of clinically useful agents. The structure-activity relationships (SAR) on a series of anticoagulant peptides with high selectivity for the enzyme thrombin are discussed. The SAR is centered on a series of di- and tripeptide arginine aldehydes based on the structure of 5l. The structural and conformational role of the amino acid residue in position 1 was investigated by substitution with conformationally restricted aromatic amino acids, aromatic acids, and a dipeptide isostere containing the psi[CH2N] amide bond replacement. Many of these peptides demonstrate potent antithrombotic activity along with selectivity toward thrombin, determined by comparison of in vitro inhibitory effects on trypsin, plasmin, factor Xa, and tissue plasminogen activator. Compound 5f, D-1-Tiq-Pro-Arg-H ¡¤ sulfate is highly active and the most selective tripeptide aldehyde inhibitor of thrombin reported to date.

Homogeneous Hydrogenation with a Cobalt/Tetraphosphine Catalyst: A Superior Hydride Donor for Polar Double Bonds and N-Heteroarenes

The development of catalysts based on earth abundant metals in place of noble metals is becoming a central topic of catalysis. We herein report a cobalt/tetraphosphine complex-catalyzed homogeneous hydrogenation of polar unsaturated compounds using an air- and moisture-stable and scalable precatalyst. By activation with potassium hydroxide, this cobalt system shows both high efficiency (up to 24 000 TON and 12 000 h-1 TOF) and excellent chemoselectivities with various aldehydes, ketones, imines, and even N-heteroarenes. The preference for 1,2-reduction over 1,4-reduction makes this method an efficient way to prepare allylic alcohols and amines. Meanwhile, efficient hydrogenation of the challenging N-heteroarenes is also furnished with excellent functional group tolerance. Mechanistic studies and control experiments demonstrated that a CoIH complex functions as a strong hydride donor in the catalytic cycle. Each cobalt intermediate on the catalytic cycle was characterized, and a plausible outer-sphere mechanism was proposed. Noteworthy, external inorganic base plays multiple roles in this reaction and functions in almost every step of the catalytic cycle.

ELECTROCHEMICAL REDUCTION OF PRISTINAMYCIN IA AND RELATED STREPTOGRAMINS IN AQUEOUS ACIDIC MEDIUM

The electrochemical reduction of the picolinoyl residue of pristinamycinIA and related streptogramins was performed at a mercury cathode, in aqueous medium.The presence of a peptidic lactone residue at the amide nitrogen atom markedly modified the expected cathodic behaviour of pyridyl carboxamides: in particular, we observed the reduction of the pyridyl ring into tetrahydropyridine derivatives.Thanks to a series of model heterocyclic carboxamides, increasing steric hindrance at the amide nitrogen position was shown to lead to enhanced reduction of the heterocyclic ring.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application In Synthesis of Isoquinoline-1-carboxylic acid, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 486-73-7, in my other articles.

Synthesis and properties of hyperbranched fluorescence/phosphorescence hybrid copolymers for white polymer light emitting devices

A series of hyperbranched fluorescence/phosphorescence hybrid copolymers with 9,9-dioctylfluorene and bis(1-phenyl-isoquinoline)(acetylacetonato)iridium(III) (Ir(piq)2acac) as the branches and the three-dimensional structured spiro[3,3]heptane-2,6-dispirofluorene (SDF, 10 mol %) as the core have been synthesized by adjusting the feeding ratios of Ir(piq)2acac (0.02-0.05 mol %). The copolymers showed good thermal and spectral stability, and amorphous film morphology because of the hyperbranched structures. The 2,7-substituted fluorenes of SDF were incorporated into the pi-system of the polyfluorene branches, and remained the Foerster resonance energy transfer (FRET) efficiency from fluorene segment to Ir(piq)2acac unit. The copolymers exhibited efficient electroluminescent characters, and white-light emission was achieved in PFSDF-Ir4 (Ir(piq)2acac 0.04 mol %)-based single layer device with CIE coordinates at (0.30, 0.34), a maximum luminance of 6777.3 cd/m2 (at 18.3 V), and a maximum current efficiency of 4.0 cd/A.
