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

Abstract

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.
