Copper-catalyzed selective oxygenation of methyl and benzyl substituents in pyridine with O2

A selective oxygenation of picolines and their derivatives has been achieved by usingasimple copper salt as a catalyst and molecular oxygen as an oxidant, where the alpha-position of the alkyl substituent is selectively oxidized to give the corresponding aldehydes or ketones. Addition of a catalytic amount of water enhances the catalytic activity, which could be attributed to the role of the proton donor to activate the substrates.

Synthesis of new chiral calix[4]arene thiourea derivatives for enantiomeric recognition of carboxylate anions

The study of enantiomeric recognition of amino acid and carboxylic acid compounds is of significance since these compounds are basic building blocks of biological molecules. Enantiomeric recognition and separation of these compounds are among the main topics of supramolecular chemistry since they are basic building blocks of biological molecules and a number of them are known to possess potent biological activities. In this study the synthesis of novel chiral calix[4]arene thiourea derivatives has been reported. The enantioselectivity of chiral receptors was investigated by using UV-Vis spectroscopy. All the chiral calix[4]arene derivatives exhibited certain chiral recognition towards the enantiomers of alpha-hydroxy isovaleric acid (HIVA), mandelic acid (MA), 2-chloromandelic acid (2-ClMA) and N-Boc-alanine (NBocAl). The receptors with hydrogen bonding sites and aromatic groups showed considerable higher stereoselectivities. As a chiral receptor, calix[4]arene 2-hydroxy-1,2 diphenyl ether thiourea derivative has enantiomeric discriminating ability for 2-chloromandelic acid (up to KR/ KS = 2.80) at 25 C. The enantiomeric recognition abilities for guests are also discussed from a thermodynamic point of view.

Oxidative degradation of AMP/MEA blends for post-combustion CO2 capture

The oxidative degradation of aqueous, concentrated 2-amino-2-methyl-1- propanol (AMP)/monoethanolamine (MEA) mixture has been investigated in batch reactors at temperatures in the range of 100-140C, and oxygen pressures in the range of 250-350 kPa. The oxidation pathway of individual AMP was proposed before attempting to investigate the oxidation of AMP/MEA blend. As compared with degradation of single MEA and AMP, no cross product was found in the degraded AMP/MEA blend under the experimental conditions. This result showed that AMP and MEA could be oxidized in parallel in the mixture. Both the overall degradation rates of MEA and AMP increased with raising temperature and oxygen partial pressure. MEA degraded faster than AMP in the blend under all the experimental conditions. The degradation rate of AMP decreased indicating MEA protects AMP from oxidation in the mixture when initial MEA concentration was increased.

Synthesis and biological evaluation of novel homochiral carbocyclic nucleosides from 1-amino-2-indanols

New chiral purinyl and 8-azapurinyl carbanucleoside derivatives based on indanol were synthesized from commercial available (1S,2S)-trans-1-amino-2- indanol and (1R,2R)-trans-1-amino-2-indanol using a linear methodology. The antiviral activity and cytotoxicity of these compounds were evaluated against herpes simplex virus type 1 (HSV-1) in Vero cells, bovine viral diarrhea virus (BVDV) in Mardin-Darby bovine kidney (MDBK) cells and hepatitis B virus (HBV) in HepG2 2.2.15 cell line. Three compounds, showed an inhibition of the HBsAg levels similar to reference drug lamivudine. One chloropurinyl nucleoside, derived from the cis-1-amino-2-indanol, was cytotoxic on MDBK cells and it could be a lead for developing anticancer agents.
