Enantioselective Synthesis of N-Benzylic Heterocycles: A Nickel and Photoredox Dual Catalysis Approach

Reported herein is a dual nickel- and photoredox-catalyzed modular approach for the preparation of enantioenriched N-benzylic heterocycles. alpha-Heterocyclic carboxylic acids, easily obtainable from common commercial material, are reported as suitable substrates for a decarboxylative strategy in conjunction with a chiral pyridine-oxazoline (PyOx) ligand, providing quick access to enantioenriched drug-like products. The presence of a directing group on the heterocyclic moiety is shown to be beneficial, affording improved stereoselectivity in a number of cases.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 126456-43-7 is helpful to your research. Reference of 126456-43-7

Configurational assignment of vic-amino alcohols from their circular dichroism spectra with dirhodium tetracetate as an auxiliary chromophore

The circular dichroism spectra of a variety of vic-amino alcohols in the presence of dirhodium tetraacetate as an auxiliary chromophore were measured in ethanol as the solvent. The method was tested with several model compounds, representing both acyclic and cyclic amino alcohols, including biologically important adrenergic drugs as well as amino sugars. The study demonstrated that the sign of the Cotton effects is determined by the preferred helicity of the O-C-C-N unit in the chiral complex formed in situ. The combined analysis of the CD, UV-vis, 1H and 13C NMR indicated predisposition to form chiral complexes by initial coordination of the amino alcohol at the axial coordination site followed by migration to the equatorial position. Finally, after migration of the ligand to an equatorial position(s) a bridging or a chelating complex is formed. Hence, vic-amino alcohols in ethanol act as bidentate ligands in the end.

Parallel microwave-assisted synthesis of ionic liquids and screening for denitrogenation of straight-run diesel feed by liquid-liquid extraction

Fifty-six ionic liquids were efficiently synthesized in parallel format under one-pot, solvent-free microwaveassisted synthesis. These compounds were evaluated as extracting agents of nitrogen-containing compounds from a real Diesel feed before being submitted to the hydrodesulfurization process to obtain ultralow sulfur Diesel. Our results showed that halogenated ionic liquids are an excellent alternative due to these ionic liquids are relatively inexpensive, presenting a high selectivity for the extraction of nitrogen-containing compounds and can be regenerated and recycled.

Polynuclear Co(II) Myrtenates with 2,4-Lutidine

Abstract: The reaction of cobalt(II) chloride with potassium myrtenate (KMyr) followed by addition of 2,3-lutidine in ethanol gives the trinuclear compound [Co3(Myr)6(2,4-Lut)2] (I). The central cobalt(II) atom is linked to each of the two other metal atoms by three myrtenic acid anions. The reaction of a solution of compound I with lithium myrtenate (LiMyr) results in the formation of tetranuclear heterometallic complex [Li2-Co2(Myr)6(2,4-Lut)2] (II). Compound II is composed of two binuclear {LiCo(Myr)3(2,4-Lut)} moieties, in which the lithium(I) atoms are linked to cobalt(II) atoms by bridging myrtenate anions. The lithium atoms are connected by two oxygen atoms of acid anions. Compounds I and II were characterized by X-ray diffraction (CIF files CCDC nos. 1898096 (I), 1898097 (II)).

Structures of the silver complexes with lutidines according to the NMR data. Crystal structure of [AgNO3(3,5-Lut)2]

The silver(I) nitrate complexes with 2,3-, 2,4-, 2,6-, and 3,5-lutidine (Lut, dimethylpyridine C7H9N), [AgNO3(Lut) 2], are synthesized and studied by multinuclear NMR (1H, 13C, and 15N) in various solvents (chloroform, dimethyl sulfoxide, and acetonitrile). The influence of steric and electronic factors of the organic ligand on the parameters of the NMR spectra is revealed. It is shown that the 15N NMR spectra are the most informative. The structure of complex [AgNO3(3,5-Lut)2] is determined. The crystals are monoclinic, space group C2/c, a = 14.599(1) A, b = 8.422(1) A, c = 12.954(1) A, beta = 99.60(1), V = 1570(2) A3, rhocalcd = 1.625 g/cm3, Z = 4. The structure is built of discrete neutral complexes [AgNO3(3,5-Lut)2]. The coordination mode of the Ag+ ion includes two nitrogen atoms of two crystallographically equivalent lutidine ligands (Ag-N 2.194(5) A, angle NAgN 147.6(3)). The nitrate ion behaves as a weak chelating ligand with respect to the Ag+ ion (Ag.O 2.674(6) A).
