[ 1 ] - A simple and green approach for the synthesis of substituted dihydro-2-oxypyrroles catalyzed by nano-Fe3O4@SiO2/SnCl4 superparamagnetic nanoparticles
In this work, an efficient and green procedure for the synthesis of dihydro-2-oxypyrroles has been developed. One-pot four-component condensation reaction of aniline derivatives (2 mmol), dialkyl acetylene dicarboxylate (1 mmol), and aldehydes ( 1 mmol) was done in ethanol at 65 °C in the presence of nano-Fe3O4@SiO2/SnCl4 as a magnetically reusable he...
