Abstract
An unprecedented eco-friendly multi-component domino approach for the synthesis of novel spiroquinazolin-2-(thi)ones and quinolin-(thio)ureas is described. The protocol proceeds via domino double [4 + 2] annulations and features an eco-benign catalyst and solvent, simple starting materials, high atom-economy, H2O as the sole by-product and a simple work-up procedure.
