▎ 摘　　要

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.
