Chemoenzymatic Dynamic Kinetic Asymmetric Transformations of β-Hydroxyketones

Herein we report on the development and application of chemoenzymatic Dynamic Kinetic Asymmetric Transformation (DYKAT) of α-substituted β-hydroxyketones (β-HKs), using Candida antartica lipase B (CALB) as transesterification catalyst and a ruthenium complex as epimerization catalyst. An operationally simple protocol allows for an efficient preparation of highly enantiomerically enriched α-substituted β-oxoacetates. The products were obtained in yields up to 95 % with good diastereomeric ratios.

Synthesis, Spectroelectrochemical Behavior, and Chiroptical Switching of Tris(β-diketonato) Complexes of Ruthenium(III), Chromium(III), and Cobalt(III)

Five tris(β-diketonato) complexes of ruthenium(III), chromium(III), and cobalt(III) [Ru(Buacac)3 (1), Ru(Oacac)3 (2), Cr(Buacac)3 (3), Cr(Oacac)3 (4), and Co(Buacac)3 (5), where Buacac = 3-butylpentane-2,4-dionato and Oacac = 3-octylpentane-2,4-dionato] with a chiral propeller-like structure have been prepared. Ligands and complexes syntheses are presented together with characterization of the compounds by 1H and 13C NMR spectroscopy, mass spectrometry, IR, UV-vis, electronic circular dichroism (ECD) spectroscopy, electrochemistry studies, and first-principles calculations. The crystal structures of 1 and 5 have also been obtained and analyzed. A comparison of the 1H NMR spectra of diamagnetic (ligands and 5) and paramagnetic (1 and 2) species is presented. Optical resolution of the five complexes has been achieved for the first time by supercritical fluid chromatography using a chiral column, giving rise to very high purity grades in all cases. ECD measurements and calculations have led to the assignment of the absolute configuration, δ or λ, of each enantiomer for 1-5. Spectroelectrochemical UV-vis and ECD studies have been performed on ruthenium λ-2 and chromium λ-4 complexes, revealing their redox-triggered chiroptical switching confirming the noninnocence character of the β-diketonate ligands.

Oxovanadium(IV) complexes bearing substituted pentane-2,4-dionate ligands: Synthesis, structure and drying activity in solvent-borne alkyd paints

New oxovanadium(IV) pentane-2,4-dionate complexes decorated with long alkyl tails have been prepared and characterized by the spectroscopic methods and the X-ray crystallography. The increased solubility in non-polar organic solvents enabled to investigate the catalytic activity of the title compounds on various solvent-borne alkyd resins. The detailed study of the drying process reveals their excellent performance at considerably lower concentrations than usual for commertial cobalt-based driers. Furthermore, the oxovanadium(IV) compounds are highly active in wider range of concentration. Such lower sensitivity to precise dosage helps to avoid the overdose effect without necessity of other additives.

Exploring Selective Inhibition of the First Bromodomain of the Human Bromodomain and Extra-terminal Domain (BET) Proteins

A midthroughput screening follow-up program targeting the first bromodomain of the human BRD4 protein, BRD4(BD1), identified an acetylated-mimic xanthine derivative inhibitor. This compound binds with an affinity in the low micromolar range yet exerts suitable unexpected selectivity in vitro against the other members of the bromodomain and extra-terminal domain (BET) family. A structure-based program pinpointed a role of the ZA loop, paving the way for the development of potent and selective BET-BRDi probes.

Different products in the reaction of the alcohols with cyclic and acyclic 1,3-dicarbonyl compounds: K5CoW12O40 as an electron transfer nano catalyst

K5CoW12O40 was used as a highly effective catalyst for the benzylation of 1,3-dicarbonyl compounds. β-Keto enol ethers were obtained when cyclic 1,3-dicarbonyl compounds used in this conditions instead of linear ones. The present methodology offers a practical, simple, mild, environmentally friendly, and time-saving method for etherification. Very low loading of catalyst, ease of workup, ease of handling, and reusability of catalyst are other advantages of this catalyst.

A cyclic porphyrin trimer as a receptor for fullerenes

(Equation Presented). A cyclic porphyrin trimer has been synthesized which has a high affinity for fullerenes. It forms 1:1 complexes with C60 and C70 with association constants of 2×106 and 2×108 M-1, respectively, in toluene. Its affinities for C86 and La@C82 are too strong to measure by fluorescence titration. The solvent dependence of the association constants shows that solvation of both the guest and the host influence the binding strength.

Synthesis of substituted 3-cyano-2-pyridones: Part IV - Influence of 3-alkyl-2,4-pentanedione and N-alkyl cyanoacetamide structure on the enzyme catalyzed synthesis of substituted 3-cyano-2-pyridones

Lipase from Candida rugosa has been used to study the influence of 3-alkyl-2,4-pentanedione and N-alkyl cyanoacetamide structure on the enzyme catalyzed reaction of pyridone ring formation in water at 40°C. Starting with 1,3-diketones and cyanoacetamides and for comparison, the expected corresponding substituted 3-cyano-2-pyridones have been synthesized by chemical methods. Bulkier substitueras lower the initial reaction rate of the enzyme catalyzed reactions and consequently the yield of the corresponding pyridones. N-alkyl cyanoacetamides are more reactive in comparison to the corresponding 3-alkyl-2,4-pentanediones with respect to the obtained yields of the corresponding substituted 3-cyano-2-pyridones.
