A novel domino protocol for three-component synthesis of new dibenzo[e,g]indoles: flexible intramolecular charge transfers
Fairly high yields of 2-aryl-3-nitrodibenzo[e,g]¬¬¬¬indoles were synthesized via a hitherto unreported domino-reaction of 9,10-phenanthrenequinone, ammonium acetate and β-nitrostyrenes in one pot. This novel three-component synthetic route is efficaciously catalysed by...
