Highly active magnetically separable CuFe2O4 nanocatalyst: An efficient catalyst for the green synthesis of tetrahydrofuro[3,4-b]quinoline-1,8(3H,4H) dione derivatives

A facile and efficient procedure has been reported for the synthesis of tetrahydrofuro[3,4-b]quinoline-1,8(3H,4H)-diones by the condensation reaction of benzaldehydes, 1,3-cyclohexanediones and anilinolactones in the presence of CuFe2O4 as a reusable nanocatalyst with high catalytic activity in water. The notable advantages of this method are excellent isolated yields, short reaction times, simple workup procedure and little environmental impact.

Synthesis of 4-azo-butenolides

An efficient, catalyst-free, microwave-assisted approach has been developed for the synthesis of 4-azo-butyenolides derivatives by condensing tetronic acid with various anilines. This approach exhibited good functional group compatibility and produced the

Synthesis of novel spirooxindoles in water by using MnFe2O 4 nanoparticles as an efficient magnetically recoverable and reusable catalyst

An efficient, clean, atom-economical and simple method for the one-pot synthesis of novel spirooxindole derivatives via a three-component reaction of isatins, dimedone and anilinolactones was reported. This reaction was performed by using MnFe2O4 nanoparticles (5 mol%) as an efficient magnetically heterogeneous catalyst in water as green solvent. Prominent among the advantages of this method is the use of magnetically recoverable and reusable catalyst, simple work up procedure, good to high product yields and use of water as a solvent that is considered to be relatively environmentally benign.
