Synthesis of Polyhydroquinoline, 2,3-Dihydroquinazolin-4(1H)-one, Sulfide and Sulfoxide Derivatives Catalyzed by New Copper Complex Supported on MCM-41
Abstract
A simple, efficient and less expensive protocol for the synthesis of Cu(II) immobilized on MCM-41@Serine has been reported. This nanohybrid material was carefully characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, inductively coupled plasma optical emission spectroscopy, X-ray diffraction, TEM, thermal gravimetric analysis, and N2 adsorption and desorption. The obtained nanostructured compound were also employed as a green, efficient, heterogeneous and reusable catalytic system for the synthesis of polyhydroquinoline, 2,3-dihydroquinazolin-4(1H)-one, sulfide and sulfoxide derivatives. High surface area, convenient recovery and reusability for several times without any significant loss of activity, the use of a commercially available, eco-friendly, cheap and chemically stable reagents, good reaction times, simple practical methodology and ease of use all make Cu(II) immobilized on MCM-41@Serine a promising candidate for potential applications in some organic reactions; makes this protocol both attractive and economically viable.
Graphical Abstract
MCM-41 nanostructured was prepared via simple and versatile procedure and directly immobilized with a new type of Cu–serine complex. After characterization of this catalyst, the catalytic activity of this nanostructure compound has been investigated for the synthesis of polyhydroquinoline, 2,3-dihydroquinazolin-4(1H)-one, sulfide and sulfoxide derivatives.
