On water: catalyst-free chemoselective synthesis of highly functionalized tetrahydroquinazolines from 2-aminophenylacrylate†
Abstract
A green and catalyst-free atom-ecomonic straightforward tandem approach for the synthesis of highly functionalized tetrahydroquinazolines by the reaction of 2-aminophenylacrylates with isothiocyanates using water as an environmentally friendly solvent via amidation and concomitant chemoselective Michael-addition is described.
