Meglumine: A novel and efficient catalyst for one-pot, three-component combinatorial synthesis of functionalized 2-amino-4H-pyrans.
An efficient one-pot synthesis of functionalized 2-amino-4H-pyrans by a meglumine-catalyzed three-component reaction has been developed. A broad range of substrates including aromatic and heteroaromatic aldehydes, isatin derivatives, and acenaphthenequinone are condensed with enolizable C-H activated compounds and alkylmalonates to give the desired products in high to excellent yields. This met...
متن کاملOne-pot three component synthesis of 2-amino-4H-chromenes under green and high efficient conditions
A simple, mild and high efficient procedure for one pot three component synthesis of 2-amino 4-H chromene derivatives was studied. The reaction was performed in water using aryl aldehydes, malononitrile and resorcinol, phloroglucinol or naphthole in the presence of N-methyl D-glucamine (Meglumine) as a green high efficient catalyst. The reaction was studied in thermal, microwave (MW) and ultras...

متن کاملA green synthesis of di-indolyloxindols catalyzed by CuO/g-C3N4 nanocomposite under mild conditions
In this study, novel CuO/g-C3N4 nanocomposite was simply synthesized by impregnation of g-C3N4 with CuO nanoparticles. Then, the heterogeneous catalyst was characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and transmission electron microscopy (...
متن کاملA Highly Efficient Protocol for the Synthesis of 2-Amidoalkylphenols using SO3H-Functionalized Phthalimide (SFP) under Solvent-free Conditions
A highly efficient and simple protocol for the synthesis of 2-amidoalkylphenols has been described. The one-pot multi-component condensation of phenols with aromatic aldehydes and amides in the presence of catalytic amount of SO3H-functionalized phthalimide (SFP) under solvent-free conditions afford the title compounds in high yields and relatively short reaction times. It is noteworthy that th...
