A Facile and Expeditious Microwave-Assisted Synthesis of Furo[3,4-<i>b</i>]indeno[2,1-<i>f</i>]quinolin-1-one Derivatives<i>via</i>Multicomponent Reaction

Abstract

A series of furo[3,4-b]indeno[2,1-f]quinolin-1-one derivatives were synthesized by the condensation of an aromatic aldehyde with tetronic acid and 9H-fluoren-2-amine in solvent of glacial acetic acid under microwave irradiation. This procedure offers several advantages including operational simplicity, clean reaction, and increased safety for small-scale high-speed synthesis.
