Abstract

Benzo[a]pyrano[2,3-c]phenazine and benzo[f]pyrano[2,3-h]quinoxaline derivatives were synthesized via a one-pot, two-step procedure from a three-component condensation reaction of 2-hydroxynaphthalene-1,4-dione, 1,2-diamines, and tetracyanoethylene in the presence of pyridine as an efficient catalyst. This novel procedure has the advantages of operational simplicity, short reaction times, easy work-up, avoiding costly syntheses, and the products do not require further purification, which provides an efficient and economical method for the synthesis of related products in excellent yields.
