Unexpected formation of new chiral 3-amino-5-alkyl-2,5-dihydro-1H-pyrrolin-2-ones from N-Boc-alpha-amino esters

We describe a one-pot process involving the DiBA1-H reduction of the ester moiety of N-protected α-amino esters, followed by Horner-Wadsworth-Emmons olefination in the presence of the trimethyl ester phosphonoglycinate carbanion allowing the formation of new chiral 3-amino-5-alkyl-2,5-dihydro-IH pyrrolin-2-one 5. The Z-enoate 4b, which is formed during this reaction, could be converted into the corresponding lactam 5b under UV irradiation with the presence of BuLi. © 2005 Elsevier Ltd. All rights reserved.

Sodium as High-efficient Catalyst in Hydroboration of Unsaturated Compounds

The catalysts used to catalyze the hydroboration of nitriles or carbodiimides usually have some disadvantages such as complex structure, high cost, large pollution of environment and so on. It is an important development direction to use the main group metals instead of the transition metals to reduce the costs and realize green catalysis. In this paper, using NaH or NaOH as a catalyst, an efficient reaction of nitrile or carbodiimide with pinacol borane (HBPin) has been achieved. It was found that 3.5 mol% of NaH participated in the hydroboration reaction in a simple and effective method under slight solvent-free circumstances. In addition, intermolecular chemoselectivity hydroboration of nitrile and substrates with different functional groups was also investigated by employing three different catalysts. This reaction uses the inorganic alkali with simple structure, commercially available and low cost to synthesize organoborane compounds, which provides ideas for industrial development.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 611-64-3, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/611-64-3.html.

Influence of the ancillary ligands on the luminescence of platinum(II) complexes with a triazole-based tridentate C boolean OR N boolean OR N luminophore

The effect of different ancillary ligands and counterions in platinum(II) complexes has been investigated. Based on the previously reported tridentate C<^>N<^>N ligand precursor 2-(1-benzyl-1H-1,2,3-triazol-4-yl)-6-phenylpyridine (HL), the photophysical properties of complexes of the type [Pt(L)(X)](n+) have been varied by changing the fourth (monodentate) ligand (X) of the square-planar platinum(II) complexes. Different lifetimes and quantum yields were observed, depending on the identity of this ancillary ligand. The most favorable photophysical properties within this series of complexes were obtained for neutral complexes with the phenylacetylido ligand with a quantum yield of 35% and a lifetime of 2.22 mu s, while for cationic complexes bearing nitrile, isonitrile and triphenylphosphane units gave comparable results with quantum yields ranging from 11% to 16% and lifetimes from 3.59 mu s to 4.93 mu s. Introducing a ferrocene moiety attached to an acetylido ligand, the complex became hardly emissive. The investigated counterions perchlorate, tetrafluoroborate and hexafluorophosphate of positively charged complexes regarding their photophysical properties were found to affect the non-radiative decay rates. To understand the minor effect observed for the emission maxima of the complexes, density functional theory (DFT) was applied. The experimental emission spectra of the complexes were reproduced by using simplified model systems. The distribution of the frontier orbitals used for the description of the emissive T-1 state in its optimized geometry mainly involves the tridentate luminophore rather than the ancillary ligand. This explains why the emission is dominated by the pincer unit with perturbative participation of the metal center while excluding significant influence of the ancillary ligand.

Discovery of 3-hydroxy-3-pyrrolin-2-one-based mPGES-1 inhibitors using a multi-step virtual screening protocol

Targeting microsomal prostaglandin E-2 synthase-1 (mPGES-1) represents an efficient strategy for the development of novel drugs against inflammation and cancer with potentially reduced side effects. With this aim, a virtual screening was performed on a large library of commercially available molecules using the X-ray structure of mPGES-1 co-complexed with a potent inhibitor. Combining fast ligand-based shape alignment, molecular docking experiments, and qualitative analysis of the binding poses, a small set of molecules was selected for the subsequent steps of validation of the biological activity. Compounds 2 and 3, bearing the 3-hydroxy-3-pyrrolin-2-one nucleus, showed mPGES-1-inhibitory activity in the low micromolar range. These data highlighted the applicability of the reported virtual screening protocol for the selection of new mPGES-1 inhibitors as promising anti-inflammatory/anti-cancer drugs.

Hydroxyapatite as a Potential Nanofiller in Technologically Useful Chlorinated Acrylonitrile Butadiene Rubber

This paper investigates the effect of hydroxyapatite nanoparticles (HA) on the cure characteristics, tensile and tear strength, elongation at break, hardness, abrasion resistance, heat build-up, resilience, glass transition temperature, oil resistance, alternating current (AC) conductivity and transport properties of chlorinated nitrile rubber (Cl-NBR). The maximum and minimum torque values were increased whereas the cure time values were decreased with the HA content in the Cl-NBR. The uniform dispersion of HA in Cl-NBR was obtained from scanning electron microscopy (SEM) and X-ray diffraction (XRD). Differential scanning calorimetry (DSC) showed the increased glass transition temperature of Cl-NBR with the addition of HA particles. Mechanical properties, conductivity and oil resistance of the composites were greatly increased with the loading of hydroxyapatite. Diffusion results were explained in terms of the loading of nanoparticles and size of the penetrant molecules. Arrhenius and thermodynamic parameters for the diffusion process have been estimated and an anomalous diffusion mechanism was observed.
