Abstract

Solvent effects on the manganese (III) initiated oxidative free radical reactions of 2-amino-1,4-naphthoquinones are described. This free radical reaction provides a novel method for the synthesis of benzo[ f]indole-4,9-diones, benzo[ f]indole-2,4,9-triones, benzo[ b]carbazole-6,11-diones and benzo[ b]acridine-6,11-diones. High chemoselectivity was observed in different solvents.
