Fast and Efficient Synthesis of 10‐Aryl‐2,7‐dimethyl‐4,5‐dioxo‐3,6,9‐trioxa‐3,4,5,6,9,10‐hexahydroanthracene under Microwave Irradiation without Catalyst
摘要:
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-dioxo3,6,9- trioxa-3,4,5,6,9,10-hexahydroanthracenes were afforded with high yields.
