The Green Procedure for the Synthesis of 1,3-oxazine-4thiones Using ZnO Nanoparticles

Abstract

A novel method for oxazine derivatives formation is established using the reaction of ammonium thiocyanate and acid chlorides with 1-naphthol in the presence of Nanoparticle of ZnO to afford [1,3]oxazine-4-thione derivatives under solvent-free conditions at room temperature in excellent yields.
