Organochalcogen compounds (containing S, Se and Te) are interesting either for use as an intermediate in the synthesis of complex molecules or for the exploitation of their biological properties. The growing in the number of papers on the synthesis and application of organochalcogen compounds has been accompanied by a concern about how they are prepared. Here, we provide a comprehensive and updated review on recent synthetic methods available for their synthesis using alternative solvents or solvent-free conditions and non-classical energy sources (microwaves irradiation, sonochemistry and mechanochemistry). Organized in fourteen sections, this review brings the more than one hundred alternative methods described so far to access organic compounds containing selenium, tellurium and sulfur.

(Chemical Equation Presented) The first catalytic asymmetric Friedel-Crafts reaction of 2-methoxyfuran with nitroalkenes was developed under the catalysis of diphenylaminetethered bis(oxazoline)-Zn(OTf)2 complexes. The reaction conditions and ligands were optimized, and the scope of the reaction was tested by varying the nitroalkenes. For most of aromatic and heteroaromatic nitroalkenes, good yields and high enantioselectivities (86-96% ee) were obtained. The methoxyfuran group in the product can be transformed to carboxylic acid via oxidative fragmentation with full retention of the configuration.

Lithiated aryl carbamates (ArLi) bearing methoxy or fluoro substituents in the meta position are generated from lithium diisopropylamide (LDA) in THF, n-BuOMe, Me2NEt, dimethoxyethane (DME), N,N,N?,N?- tetramethylethylenediamine (TMEDA), N,N,N?,N?- tetramethylcyclohexanediamine (TMCDA), and hexamethylphosphoramide (HMPA). The aryllithiums are shown with 6Li, 13C, and 15N NMR spectroscopies to be monomers, ArLi-LDA mixed dimers, and ArLi-LDA mixed trimers, depending on the choice of solvent. Subsequent Snieckus-Fries rearrangements afford ArOLi-LDA mixed dimers and trimers of the resulting phenolates. Rate studies of the rearrangement implicate mechanisms based on monomers, mixed dimers, and mixed trimers.

Electric Literature of 21436-03-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a patent, introducing its new discovery.

The structure of the title double salt, [Cr(rac-chxn)3][ZnCl4]Cl 3H2O (chxn is trans-1,2-cyclohexanediamine; C6H14N2), has been determined from synchrotron data. The CrIII ion is coordinated by six N atoms of three chelating chxn ligands, displaying a slightly distorted octahedral coordination environment. The distorted tetrahedral [ZnCl4]2- anion, the isolated Cl- anion and three lattice water molecules remain outside the coordination sphere. The Cr – N(chxn) bond lengths are in a narrow range between 2.0737(12) and 2.0928(12)A; the mean N – Cr – N bite angle is 82.1(4). The crystal packing is stabilized by hydrogen-bonding interactions between the amino groups of the chxn ligands and the water molecules as donor groups, and O atoms of the water molecules, chloride anions and Cl atoms of the [ZnCl4]2- anions as acceptor groups, leading to the formation of a three-dimensional network. The [ZnCl4]2- anion is disordered over two sets of sites with an occupancy ratio of 0.94:0.06.

In this manuscript, we describe the synthesis of new trans-N-sulfonamide platinum complexes and their antiproliferative activity (GI50, muM) in human solid tumors cells. The structure activity relationships (SAR), with different new synthesized complexes by variation in ligand, halogen and also in the stereochemistry of the ligand, has been studied. Solubility and stability studies have also been carried out as well as fluorescent cell assays in order to clarify the final target in the tumor cells.
