MCM-BP as a Novel Nanomagnetic Reusable Basic Catalyst for the one Pot Solvent-Free Synthesis of Dihydropyridine, Polyhydroquinoline and Polyhydroacridine Derivatives via Hantzsch Multicomponent Condensation Reaction
By the immobilization of bipyridinium chloride onto mesoporous MCM-41encapsulated Fe3O4 nanoparticles via a simple post-synthesis method, a totally new organic-inorganic hybrid nanocomposite was formulated. The heterogeneous hybrid nanomagnetic composite was characterized by <spa...
متن کاملA One-pot Multi-component Synthesis of Dihydropyrimidinone/Thione and Dihydropyridine Derivatives via Biginelli and Hantzsch Condensations using t-BuOK as a Catalyst Under Solvent-free Conditions
The synthesis of various substituted Biginelli 3,4-dihydropyrimidinone/thione and Hantzsch 1,4dihydropyridine derivatives has been achieved using a modified procedure in the presence of potassium ter-butoxide (tBuOK) as a catalyst under solvent-free conditions, in good to excellent yields.
متن کاملSolvent-free mechanochemical and one-pot reductive benzylizations of malononitrile and 4-methylaniline using Hantzsch 1,4-dihydropyridine as the reductant.
Under mechanical milling conditions, direct reductive benzylizations of malononitrile and 4-methylaniline by aromatic aldehydes were achieved using a Hantzsch 1,4-dihydropyridine as the reductant.
متن کاملOne-pot synthesis of functionalized thiazolidine-4-ones from thiosemicarbazone derivatives and activated acetylenes in water as a green solvent
Some 2-iminothiazolidin-4-ones have been synthesized by the reaction of dialkyl acetylenedicarboxylates with thiosemicarbazones. The reaction was performed in the presence of 10 mol% of triphenylphosphine and tetrabutylammonium bromide as a phase transfer catalyst in water as a green solvent. All the synthesized compounds were characterized by their physical and spectral data.
