Acid-Free Silver-Catalyzed Cross-Dehydrogenative Carbamoylation of Pyridines with Formamides

Primary pyridylcarboxamides are prevalent parent structures in bioactive molecules and have the apparent advantages over N-protected derivatives as synthetic building blocks. However, no practical methods have been developed for direct synthesis of this compound class from unfunctionalized pyridines. We herein present a general, safe, concise, acid-free, and highly selective method for the C2-carbamoylation of pyridines with unprotected formamide and N-methyl formamide through the cleavage of two C-H bonds.

15N NMR Spectroscopy of Some Azines

15N NMR shielding data are presented for 56 cyclic azines in 0.5 M dimethyl sulfoxide solutions with 0.01 M increments of Cr(acac)3 added for each nitrogen atom in the molecules.For the polyazines, the 15N signal assignments were based on 2J(NH) interactions and some INDO/S-SOS shielding calculations.The effects of alpha-, beta- and gamma-methyl and conjugated ring substitution on nitrogen shielding are presented and discussed, as are the influences arising from fusion with alicyclic and aromatic rings at various positions.The effects of a second nitrogen atom on the shielding of the first one are shown to be critically dependent on both their relative positions and on the position of fusion of conjugated ring systems.

Iron-Catalyzed 1,2-Selective Hydroboration of N-Heteroarenes

A N2-bridged diiron complex [Cp?(Ph2PC6H4S)Fe]2(mu-N2) (1) has been found to catalyze the hydroboration of N-heteroarenes with pinacolborane, giving N-borylated 1,2-reduced products with high regioselectivity. The catalysis is initiated by coordination of N-heteroarenes to the iron center, while the B-H bond cleavage is the rate-determining step.

Reactions on polymers with amine groups. IV1: Studies on the reaction of some pyridine compounds with alpha, beta-unsaturated carboxylic acids

The reaction of pyridine and methylpyridines with alpha, beta-unsaturated carboxylic acids, such as: acrylic, methacrylic, crotonic, cinnamic, itaconic, fumaric and maleic acid, as well as the reactions of di- and trimethylpyridines with acrylic and maleic acids were studied. The reactions developed by such compounds may be, actually, considered as a competition between addition and neutralization, resulting betaine and/or salt. The factors influencing the development reaction are the chemical structure of the amine, acid and solvent, as well as the reaction duration. The order of reactivity for the same reactions was established by half-times. The 1H-NMR methodology was applied for elucidating both the chemically obtained structures and the half-times.

Parallel solution-phase synthesis and general biological activity of a uridine antibiotic analog library

A small library of ninety four uridine antibiotic analogs was synthesized, under the Pilot Scale Library (PSL) Program of the NIH Roadmap initiative, from amine 2 and carboxylic acids 33 and 77 in solution-phase fashion. Diverse aldehyde, sulfonyl chloride, and carboxylic acid reactant sets were condensed to 2, leading after acid-mediated hydrolysis, to the targeted compounds 3-32 in good yields and high purity. Similarly, treatment of 33 with diverse amines and sulfonamides gave 34-75. The coupling of the amino terminus of d-phenylalanine methyl ester to the free 5?-carboxylic acid moiety of 33 followed by sodium hydroxide treatment led to carboxylic acid analog 77. Hydrolysis of this material gave analog 78. The intermediate 77 served as the precursor for the preparation of novel dipeptidyl uridine analogs 79-99 through peptide coupling reactions to diverse amine reactants. None of the described compounds show significant anticancer or antimalarial acivity. A number of samples exhibited a variety of promising inhibitory, agonist, antagonist, or activator properties with enzymes and receptors in primary screens supplied and reported through the NIH MLPCN program.

Selective amidation of unprotected amino alcohols using surfactant-in-water technology: A highly desirable alternative to reprotoxic polar aprotic solvents

A general selective and environmentally friendly method for the formation of amide bonds using a surfactant in water as medium is described. The use of readily available 1-ethyl-3-(3-(dimethylamino)propyl)-carbodiimide (EDC) and hydroxybenzotriazol (HOBt) as a coupling system, N-methylmorpholine (NMM), and TPGS-750-M represents mild conditions allowing for chemoselective amidation of unprotected amino alcohols. Comparative results with classical polar aprotic solvents such as dimethylformamide or acetonitrile are presented.

New pi-arene ruthenium(II) piano-stool complexes with nitrogen ligands

The synthesis, characterization, DNA interaction and antiproliferative behavior of new pi-arene ruthenium(II) piano-stool complexes with nitrogen ligands are described. Three series of organometallic compounds of formulae [RuCl2(eta6-p-cym)L] were synthesized (with L = 2-, 3- or 4-methylpyridine; L = 2,3-, 2,4-, 2,5-, 3,4-, 3,5-dimethylpyridine and L = 1,2-, 1,3- 1,4-methylaminobenzene). The crystal structures of [RuCl 2(p-cym)(4-methylpyridine)], [RuCl2(p-cym)(3,4- dimethylpyridine)] and [RuCl2(p-cym)(1,4-methylaminobenzene)] were resolved and the characterization was completed by spectroscopic UV-vis, FT-IR and 1H NMR studies. Electrochemical experiments were performed by cyclic voltammetry to estimate the redox potential of the Ru(II)/Ru(III) couple. The interaction with plasmid pBR322 DNA was studied through the examination of the electrophoretical mobility and atomic force microscopy, and interaction with ct-DNA by circular dichroism, viscosity measurements and fluorescence studies based on the DNA-ethidium bromide complex. The antiproliferative behavior of the series with L = methylpyridine was assayed against two tumor cell lines, i.e. LoVo and MiaPaca. The results revealed a moderate cytotoxicity with a higher activity for the LoVo cell line compared to the MiaPaca one.
