Abstract

In this work, starch nanoparticles as a green and cheap catalyst were obtained based on the precipitation of amorphous starch in ethanol. It was found that starch nanoparticles are efficient catalyst for the synthesis of 2-aminothiazoles using methylcarbonyl compounds and thiourea as precursors. The use of green and biodegradable nanostarch makes this present methodology quite simple, shorter reaction times and milder conditions, and more convenient and economically viable compared to catalyzed methods reported in the literature.
