An efficient methodology employing copper nanoparticles for the preparation of 2-naphthol condensed 1,3-oxazinone derivatives employing one-pot condensation reaction in the presence of K 2 CO 3 and copper nanoparticles in PEG-400 is described which offers several advantages, viz. high yields, clean reaction, short reaction times, recyclability of the catalyst and simple workup procedure...
A simple, efficient, stereoselective, one pot three component condensation reaction between thiazolidine-2,4-dione, aldehyde and amine derivatives using monodispersed, recyclable and inexpensive Cu-nanoparticles for the synthesis of thiazolidine-2,4-dione derivatives in excellent yields and high purity has been described here for the first time.
