Preparation of 1-amidoalkyl-2-naphthol derivatives using barium phosphate nano-powders

Barium phosphate (Ba-3(PO4)(2)) nano-powder was successfully synthesized via a simple precipitation route without any surfactant. The prepared nano-powder was applied for the facile synthesis of 1-amidoallcyl-2-naphthol derivatives using multi-component reaction of aldehydes, 2-naphthol and an amide (or urea) in high yields.
