In a new multicomponent reaction phenanthridine reacts with isocyanides and malonitrile in the presence of benzaldehyde derivatives to produce 2-aryl-3-(alkyl- or arylimino)-2,3-dihydropyrrolo[1,2-f]phenanthridine-1,1(12b H)-dicarbonitrile in a simple, mild, and efficient protocol in excellent yields.
An efficient synthesis of thiophene derivatives is described via one-pot reaction between ammonium thiocyanate, acyl chlorides, α-halocarbonyls, and enaminones under solvent-free conditions at 65 °C. The mild reaction conditions and high yields of the products exhibit the good synthetic advantage of these methods.
This study was focused on evaluation of the cytotoxicity and apoptotic affects of benzofuran derivative on MCF-7 breast cancer cell line. This effective compound was isolated from the root of Petasites hybridus plant. For experiments, the MCF-7 cells were treated with several concentrations (0-500μM) of 1-(6-hydroxy-2-… (More)
An effective one-pot synthesis of dialkoxyphosphoryl-2-oxo-2H-pyran derivatives by three-component reaction of alky bromides and dialkyl acetylenedicarboxylates in the presence of trialkyl phosphite is described. The reactions were performed under solvent-free conditions at 50°C and neutral conditions and provided good yields of products.
In the title compound, [Cu(C(5)H(7)O(2))(C(2)N(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is five-coordinated in a square-pyramidal geometry with two acetyl-acetonate O and two phenanthroline N atoms forming the base. The apical position is occupied by the central N atom of the dicyanamide ligand. The dicyanamide N atoms are each involved in hydrogen bonds… (More)
Three- component reactions of 1-(6-hydroxy-2-isopropenyl-1-benzofuran-yl)-1-ethanone, aldehydes and malononitrile or ethyl cyanoacetate in the presence of nanoparticles of ZnO as catalyst are explained as effective and green synthetic method for generating 9H- furo[2,3-f]chromenes in good yield.
A one-pot synthesis of cyclopentanone derivatives from phosphorus ylide under lab-type microwave assisted methodology was described. The phosphorus ylides were obtained via the reaction of activated acetylenic compounds, ethyl 4-chloroacetoacetate and triphenylphosphine. The structure of phosphorus ylides was assigned by ¹H, ¹³C and ³¹PNMR. The phosphorus… (More)
Thiazole derivatives are produced by using one-pot multicomponent reactions of acid chlorides, potassium thiocyanate, amino acids, alkyl bromides and ZnO nanorods (NR-ZnO) as the catalyst in water at ambient temperature. These reactions were not performed without using NR-ZnO as the catalyst. Nanorods of ZnO have been prepared by reflux procedure using… (More)
Studies on the interactions between metallodrugs and human serum albumin (HSA), as carrier for drugs and biological molecules, are extremely important to design and discover new drugs. The interaction of three novel synthesized complexes of [Pd(phen)(R-gly)]NO3, where R-gly is methyl-, propyl-, and amyl-glycine and phen is 1,10- phenanthroline, with HSA… (More)
An efficient synthesis of functionalized tetrahydroimidazoles via a one-pot tandem reaction between ninhydrin, primary alkylamines, arylisocyanates or arylisothiocyanates, acetylenic esters and triphenylphosphine is described.
