Abstract

A simple, straight for ward and highly efficient protocol has been developed for the one-pot multicomponent synthesis of 1, 8-dioxo-octahydroxanthenes from the reaction of aromatic aldehydes and dimedone, and also N -aryl-1, 8-dioxodecahydroacridines from aromatic aldehydes, dimedone and aromatic amines in excellent yields using ammonium chloride as a low-cost and non-toxic eco-friendly catalyst under solvent-free conditions. The salient features of the present protocol are the operational simplicity, clean reaction profiles, excellent yields, high atom-economy, relatively short reaction-time as well as the use of inexpensive and environmentally benign catalyst.
