Abstract
An effective and advantageous one-pot multicomponent photo-induced methodology has been developed for the synthesis of biologically potent 2-amino-4H-1,3-oxa/thiazine from substituted benzaldehyde, ethynylbenzene and urea/thiourea catalyzed by eosin-Y at room temperature using EtOH as a green solvent with wide range of applications in pharmaceutical and agriculture industries. This proposed work emphasizes to investigate an accessible, safe, easy and convenient method for the synthesis of 2-amino oxa/thiazine derivatives with good to excellent yield.
