The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and their interactions with reaction intermediates and transition states. In an article, 492-08-0, name is (+)-Sparteine, introducing its new discovery. category: chiral-nitrogen-ligands

The lupin alkaloid sparteine is a well-known chiral diamine with a range of applications in asymmetric synthesis, as well as a blocker of voltage-gated sodium channels (VGSCs). However, there is only scarce information on the VGSC-blocking activity of sparteine derivatives where the structure of the parent alkaloid is retained. Building on the recent renewed availability of sparteine and derivatives we report herein how modification of sparteine at position 2 produces irreversible blockers of VGSCs. These compounds could be clinically envisaged as long-lasting local anesthetics.

A series of enantiopure ligands based on the aminoindanol scaffold, but differing in regio-and stereochemistry has been synthesized. These ligands have been conveniently derivatized and their catalytic efficiency in different enantioselective reactions has been screened to determine privileged candidates with respect to regio- and stereochemistry for each considered process. The nature of the amino substituent has been optimized for specific applications and this has led to the development of an efficient method for the preparation of bulky bicyclic amines by reductive amination.

A method to measure the rate constant for the formation of symmetrical proton-bound dimers at ambient pressure was proposed. The sample is continuously delivered to the drift region of an ion mobility spectrometer where it reacts with a swarm of monomer ions injected by the shutter grid. Dimer ions are formed in the drift tube and a tail appears in the ion mobility spectrum. The rate constant is derived from the mobility spectra. The proposed approach was typically examined for methyl isobutyl ketone (MIBK), 2,4-dimethyl pyridine (DMP), and dimethyl methyl phosphonate (DMMP). The rate constants measured in this study were: 0.25 × 10-9, 0.86 × 10-10, and 0.47 × 10-10 cm3 s-1 for MIBK, DMP and DMMP, respectively. The logarithm of the measured rate constants were found to be almost independent of reciprocal temperature within 303 to 343 K, indicating that no activation energy is involved in the formation of proton-bound dimers.

Lignocellulosic biomass is considered an abundant and renewable source to produce bio-oils with an objective of its value addition for fuels and chemicals. Upgrading strategies have immensely evolved as a result of ever progressing research in this field. Development of complete analytical protocol for bio-oil characterization at different stages of its production, storage, upgrading and during its use is essential for the purpose of its quality assurance and understanding. This report is aimed at developing a sample preparation procedure for bio-oils involving an extensive liquid-liquid extraction approach. Bio-oil obtained after slow pyrolysis of Jatropha Curcas seed cake was phase separated and subjected to solvent extraction. Various solvents were screened for their extraction capabilities towards available organic compounds of all functional group in the bio-oil. Ethyl acetate, dichloromethane, carbon tetrachloride, diethyl ether, benzene, cyclohexane and hexane were employed for extraction of aqueous phase under similar conditions. Recoveries of compounds containing varying functional groups indicated ethyl acetate and dichloromethane as optimum among all other solvents. During the extraction, partitioning of compounds between bio-oil phase and solvent occurred largely on the basis of polarity. Acidic and basic organic compounds present in the aqueous phase were determined after adjusting the pH of samples followed by dichloromethane extraction. A comprehensive detail of the extracted chemicals and their classification has been provided. The identification was carried out qualitatively with GC-MS and derivatization of polar chemicals was also carried out before analysis. These experiments compare the efficacy of various organic solvents for extracting diverse bio-oil pyrolytic products. The findings are important in ascertaining usefulness of organic solvents towards enrichment of available bio-oil chemical groups. The information may be either utilized for characterization purposes or their monitoring during upgrading process.
