l-Proline-modified magnetic nanoparticles (LPMNP): a novel magnetically separable organocatalyst

Abstract

This study offers a new and efficient method for the stabilization of L-proline moieties on magnetic nanoparticles in order to prepare a novel magnetic recyclable organocatalyst for application in organic transformations. The catalytic activity of this heterogeneous organocatalyst was evaluated in the condensation reaction of indoles and aldehydes for the synthesis of bis(indolyl)methanes in water.
