One-Pot Three-Component Synthesis of 1-(α-Aminoalkyl)-2-Naphthols Using Nano-[Ni-4MSP](NO₃)₂ as a New Catalyst

Abstract

7-amino-5-(4-methoxyphenyl)-2,4-dioxo-2,3,4,5-tetrahydro-1H-pyrano[2,3-d]pyrimidine-6-carbonitrile was prepared as an amine and then reacted with salicylaldehyde and Ni(NO₃)₂.6H₂O to afford nano–Ni-[4-methoxyphenyl-salicylaldimine-pyranopyrimidine dione] (NO₃)₂ {Nano-[Ni-4MSP](NO₃)₂} as a new Schiff base complex in nano size. Nano-[Ni-4MSP](NO₃)₂ as a new complexes was fully characterized by various analyses and successfully used as an effectual catalyst for the synthesis of some 1-($\alpha$ -Aminoalkyl)-2- naphthols.
