Using oxygen as the sole oxidant for two steps, we developed a new method to synthesize beta-aryl alpha,beta-enones by fine-tuning the Pd(ii)-catalyzed oxidation of allyl alcohol to subsequent arylation with arylboronic acids, arylboronic ester and aryltrifluoroborate salt. This one-pot green method does not require copper salt, base, and intermediate isolation. Halogen-bearing chalcones, dibenzylideneacetones and arylalkyl enones were synthesized in good yields.

The (+)-sparteine-mediated lithiation-substitution of o-benzyl-N- pivaloylaniline with various ketones was investigated. The obtained highly enantioenriched tertiary alcohols were used for the synthesis of alkenyl-substituted products 12 and 13 as well as 3,3,4-trisubstituted tetrahydroquinoline derivatives 22-24. The reaction with alpha,beta- unsaturated ketones afforded highly enantioenriched 1,4-addition products 28-33 and provided a protocol for the asymmetric synthesis of highly substituted tetralin derivative 34.

Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. name: 1,5-Diphenylpenta-1,4-dien-3-one,

We report on the synthesis of a variety of C,E-bidentate triazolylidene ruthenium complexes that comprise different donor substituents E (E = C: phenyl anion; E = O: carboxylate, alkoxide; E = N: pyridine at heterocyclic carbon or nitrogen). Introduction of these donor functionalities is greatly facilitated by the synthetic versatility of triazoles, and their facile preparation routes. Five different complexes featuring a C,E-coordinated ruthenium center with chloride/cymene spectator ligands and three analogous solvento complexes with MeCN spectator ligands were prepared and evaluated as catalyst precursors for direct base- and oxidant-free alcohol dehydrogenation, and for transfer hydrogenation using basic iPrOH as a source of dihydrogen. In both catalytic reactions, the neutral/mono-cationic complexes with chloride/cymene spectator ligands performed better than the solvento ruthenium complexes. The donor functionality had a further profound impact on catalytic activity. For alcohol dehydrogenation, the C,C-bidentate phenyl-triazolylidene ligand induced highest conversions, while carboxylate or pyridine donor sites gave only moderate activity or none at all. In contrast, transfer hydrogenation is most efficient when a pyridyl donor group is linked to the triazolylidene via the heterocyclic carbon atom, providing turnover frequencies as high as 1400 h-1 for cyclohexanone transfer hydrogenation. The role of the donor group is discussed in mechanistic terms.

A simple homogeneous catalytic system based on nickel phosphine complexes has been developed for the transfer hydrogenation and condensation of alpha,beta-unsaturated ketones to yield saturated ones and saturated imines using primary amines as hydrogen donors. Thus, a wide range of fluorinated 1,5-diaryl-1,4-pentadiene-3-ones were allowed to react with substituted benzylamines in the presence of [(dippe)Ni(mu-H)]2 (dippe = 1,2-bis-(diisopropylphosphino)-ethane) using ethanol as a solvent at 180 C to give the corresponding saturated carbonyl compounds; here hydrogenation of the CC bond was preferred over the CO bond. Under the same reaction conditions but using an excess of benzylamine, a tandem process is then favoured, starting also with the reduction of the CC bond followed by a nucleophilic addition of the primary amine to yield valuable saturated imines with good to excellent yields (62%-91%).

Two series of chalcone based sulfone and bisulfone derivatives were synthesized using chalcone, thiophenol and sodium metal at room temperature, followed by oxidation of chalcone sulfides with m-CPBA at 0 C in a novel method. Both sulfones and bisulfones were evaluated for their antimicrobial activities against Aspergillus niger and Candida albicans (yeast), Bacillus subtilis and Staphylococcus aureus (Gram (+) bacteria) and Pseudomonas aeruginosa and Salmonella typhimurium (Gram (-) bacteria) strains. Among them, compounds 2c, 3c, 6c, 7c, 8c and 9c have shown high antifungal activity against C. albicans compare to reference drugs viz. Amphotericin-B and Nystatin.

The infrared and vibrational circular dichroism (VCD) spectra of six chiral oxorhenium(V) complexes, bearing a hydrotris(1-pyrazolyl)borate (Tp) ligand, have been investigated. These complexes are promising candidates for observation of parity violation (symmetry breaking due to the weak nuclear force). New chiral oxorhenium complexes have been synthesized, namely, [TpReO(eta 2-O(CH3)CH2CH2O-O,O)] (4a and 4b) diastereomers and [TpReO(eta2-N(CH3)CH 2CH2O-N,O)] (5) and [TpReO(eta2-N(tBu)CH 2CH2O-N,O)] (6) enantiomers. All compounds could be obtained in enantiomerically pure form by using either column chromatography or HPLC over chiral columns. VCD spectroscopy of these compounds and of [TpReO(eta2-N(CH3)CH(CH3)CH(Ph)O-N,O)] (2) and [TpReO(eta2-N(CH2)3CHCO2-N,O)] (3) (with chiral bidentate ligands derived, respectively, from ephedrine and proline) were studied. This allowed the absolute configuration determination of all compounds together with their conformational analysis, by comparing calculated and experimental spectra. This is the first VCD study of rhenium complexes which further demonstrates the applicability of VCD spectroscopy in determining the chirality of inorganic complexes.
