Abstract
A fast and efficient synthetic method for the title compounds is described. By heating aromatic aldehyde and triacetic acid lactone in ethylene glycol under microwave irradiation without catalyst for 3–5 min, 10‐aryl‐2,7‐dimethyl‐4,5‐dioxo‐3,6,9‐trioxa‐3,4,5,6,9,10‐hexahydroanthracenes were afforded with high yields.
