AgI nanoparticles were discovered to be an effectual heterogeneous nanocatalyst for the preparation of (amidoalkyl)naphthol and oxazine derivatives under solvent-free conditions. The advantages of the present approach are short reaction times, moderate temperature, premier yields, eco-friendly reaction conditions, simple purification and good reusability of the catalyst.

The present report describes a solvent-free synthesis of 1-amidoalkyl-2-naphthols and 1,2-dihydro-1arylnaphth[1,2-e][1,3]oxazin-3-ones via one-pot multicomponent reaction of 2-naphthol, aryl/heteryl aldehyde, and amide/urea in presence of graphene oxide as an eco-benign heterogeneous catalyst in good to excellent yields. The catalyst is easily recoverable and reusable. (C) 2016 Elsevier Ltd. All rights reserved.
