Abstract

Abstract Benzimidazole-4, 7-diones 3a and 3b were synthesized and submitted to hetero Diels–Alder reactions with azadienes 4 and 5 to afford imidazo [4, 5-g] quinoline-4, 9-diones 6–9. The structure of the latter was assigned by X-ray diffraction, 1 H NMR NOE DIFF experiments or by a molecular dynamics study.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
