Visible-light-mediated efficient conversion of aldoximes and primary amides into nitriles

A photosensitization-based approach for a convenient and efficient conversion of aldoximes and primary amides into nitriles is reported. The protocol involves eosin Y catalysed, visible-light-mediated in situ formation of the Vilsmeier-Haack reagent from CBr4 and a catalytic amount of DMF, which brings about the desired transformation to afford nitriles at r.t.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 41717-32-2 is helpful to your research. 41717-32-2

Studies directed toward total synthesis of rhodocomatulins: A regioselective synthesis of brominated hydroxyanthraquinones by anionic annulations

In this work, brominated hydroxyanthraquinones, which are the core structural motif of naturally occurring bromorhodocomatulins, were successfully synthesized using Hauser annulation reaction as the key step. When brominated Michael acceptors (brominated p-quinone monoketals) and cyanophthalides or bromocyanophthalides (Hauser donors) were reacted under the annulation conditions, brominated anthraquinones were obtained with 81?87% yields for four examples. On acidic quenching, products were obtained as solid which were separated by filtration and purified by recrystallization in acetone. No chromatography was required.

Controlled Reduction of Carboxamides to Alcohols or Amines by Zinc Hydrides

New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)? is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.

A new 3D conceptual structure modeling of biochars by molecular mechanic and molecular dynamic simulation

Purpose: The combination of analytical chemistry and simulation methods provides more complete information about biochars. Materials and methods: The biochars prepared by pyrolysis of the crop straw at 300 and 500?C were investigated by elemental analysis, pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and solid-state 13C nuclear magnetic resonance (NMR) spectrometry to build the 2D structural models of biochars. The most stable and balanced 3D conformations were gained by optimizing in the optimized potential for liquid simulation (OPLS) force field of molecular mechanic and molecular dynamic simulation of HyperChem software. Results and discussion: There were few O-containing and N-containing compounds in biochars. According to the results of Py-GC-MS, 41 and 28 pyrolysis products were identified for the building of the conceptual models of 300 and 500?C biochars. Solid-state 13C NMR data also demonstrated that there were very high values of unsaturated C in biochars. The agreement between elemental concentration and chemical functional groups of two simulated models and experimental biochars was successfully achieved. Quantitative structure activity relationship (QSAR) properties were calculated and indicated the correlation of molecular structures with properties such as surface area, volume, polarizability, refractivity, and hydration energy. Conclusions: The conceptual structural models of corn straw biochars produced at 300 and 500?C were C78H68N2O25 and C59H29NO10, respectively. The simulation results showed that the 3D structure of the 300?C biochar with ?4 charges and the nonprotonated 3D structure of the 500?C biochar were the most stable. Deprotonation reaction is an endothermic process.

Access to Multifunctionalized Benzofurans by Aryl Nickelation of Alkynes: Efficient Synthesis of the Anti-Arrhythmic Drug Amiodarone

An unconventional nickel-catalyzed reaction was developed for the synthesis of multifunctionalized benzofurans from alkyne-tethered phenolic esters. The transformation involves the generation of a nucleophilic vinyl NiII species by the regioselective syn-aryl nickelation of an alkyne, which then undergoes an intramolecular cyclization with phenol ester to yield highly functionalized 1,1-disubstituted alkenes with 3-benzofuranyl and (hetero)aryl substituents. The methodology can be used for the late-stage benzofuran incorporation of various drug molecules and natural products, such as 2-propylvaleric acid, gemfibrozil, biotin, and lithocholic acid. Furthermore, this arylative cyclization method was successfully applied for the efficient synthesis of the anti-arrhythmic drug amiodarone.

Inhibitors of the fibroblast growth factor receptor

Signaling through the fibroblast growth factor receptor (FGFR) tyrosine kinase is crucial to a number of key pharmacological processes; however, dysregulation of this signaling is observed with a number of different cancers suggesting that inhibition of FGFR may provide an important therapeutic agent in the treatment of cancers. This chapter provides an overview of the development of FGFR inhibitors beginning with the identification of nonselective FGFR inhibitors, then describing the medicinal chemistry optimization resulting in the delivery of a number of highly selective FGFR inhibitors, some of which are currently being assessed in clinical trials. The development of isoform selective FGFR inhibitors as well as covalent inhibitors and inhibitors of the inactive form of FGFR are also described.
