The catalytic highly regio-, diastereo-, and enantioselective synthesis of a small library of spiropyrrolizidineoxindolesvia a four-component 1,3-dipolar cycloaddition reaction of azomethine ylides, derived from isatin, with electron-deficient dipolarophilewas described. The process occurs at room temperature in aqueous ethanol as a green solvent and in the presence of a bidendatebis(imine)–Cu(...

Substituted 2, 4- diphenyl quinolines were synthesized by a multicomponent domino reaction of anilines, aldehydes and terminal aryl alkynes. The synthetic pathway involves the formation of an imine, followed by the intermolecular addition of an alkyne to the imine. This intermediate immediately undergoes ring closure and oxidative aromatization. The reaction is catalyzed by natural kaolin, a st...

With the aim of obtaining information about drug-drug interaction (DDI) between acetaminophen and some of antidepressant drugs (fluoxetine, sertraline and nortriptyline), in the present work we studied the electrochemical oxidation of acetaminophen (paracetamol) in the presence of these drugs by means of cyclic voltammetry and Controlled-potential coulometry. The reaction between N-acetyl-p-ben...

A series of novel Pd(ii) complexes with chelating mono(imidazolin-2-imine) and bis(imidazolin-2-imine) ligands were synthesized. The crystal structures of [Pd(DMEAIm(iPr))Cl2] and [Pd(DPENIm(iPr))Cl2] were determined by X-ray diffraction analysis. The reactivity of the six Pd(ii) complexes, namely, [Pd(en)Cl2], [Pd(EAIm(iPr))Cl2], [Pd(DMEAIm(iPr))Cl2], [Pd(DPENIm(iPr))Cl2], [Pd(BL(iPr))Cl2] and...

This work presents the pH sensing ability of a fluorescent indolin‐3‐imine derivative. Protonation weakly basic imine (pKa = 8.3 its conjugate acid) results in significant redshift absorption band. The fluorophore acts as photobase, with basicity increase approximately 6 units upon photoexcitation. behavior promotes excited state proton transfer from weak acids such protic solvents. characteris...

Synthesized of novel metal (II)- tetra-4-(N,N-dimethyl phenyl) methan-imine phthalocyanines (MTDMPhImPc) [ M = Co, Ni, Cu, Zn] by an effective and suitable method. The tetra-nitrophthalocyanines converted into aminophthalocyanines reduction. Than amino derivatives bearing to form tetra substituted 4-(N,N-dimethyl methane-imine complexes. These compounds were characterized FTIR, elemental analys...

A one-pot reaction of an equimolar mixture 4-methoxyaniline, phenyl isothiocyanate, and 2-bromoacetylbenzofuran in absolute ethanol the absence any catalysts afforded 4-(benzofuran-2-yl)-3-(4-methoxyphenyl)-N-phenylthiazol-2(3H)-imine with 83% yield. Under similar conditions, 4-flouroaniline provided a expected 4-(benzofuran-2-yl)-3-(4-fluorophenyl)-N-phenylthiazol-2(3H)-imine unexpected 4-(ben...
