    Description / Table of Contents: Zusammenfassung Die Titelverbindungen5 wurden in zwei Stufen aus den entsprechenden Isoindolo[2,1–b]isochinolin-5(7H)-onen (3) dargestellt, die ihrerseits in hohen Ausbeuten aus 3-Ethoxy-1H-isoindolen (2) und Homophthalsäureanhydriden erhältlich sind. DieStevens-Umlagerung von5 führte zu 2-Methyl-2,3-dihydro-1H-isoindol-1-spiro-2′-indanen (6).
    Notes: Abstract The title compounds5 were synthetized in two steps from the corresponding isoindolo[2,1–b]isoquinoline-5(7H)-ones3, obtained in high yields from 3-ethoxy-1H-isoindoles2 and homopthalic anhydrides1. TheStevens rearrangement of5 gave 2-methyl-2,3-dihydro-1H-isoindole-1-spiro-2′-indanes6.

    Description / Table of Contents: Reaktionen von Glutacon- und Homophthalsäureanhydriden mit Imidoestern, Imidoylchloriden und 1-ChlorisochinolinGlutaconsäureanhydrid (9) reagiert mit N-substituierten Benzimidoylchloriden 3 zu den entsprechenden (Z)-3-[(Amino)(phenyl)methylen]pyrandionen 12 und mit 1-Chlorisochinolin (4) zum Benzo[a]chinolizinon 13. Die Umsetzung von α-Methylhomophthalsäureanhydrid (10) mit 3 und dem Imidat 7 liefert die 1 (2H)-Isochinolinone 14 bzw. 19 und die mit 4 das 13-Methyldibenzo-[a,g]chinolizinon 15. Die zu α-Kondensationsprodukten führende Reaktion von 1a, b mit 3 wird untersucht.
    Notes: Glutaconic anhydride (9) reacts with N-substituted benzimidoyl chlorides 3 to give the corresponding (Z)-3-[(amino)(phenyl)methylene]pyrandiones 12, whereas with 1-chloroisoquinoline (4) the benzo[a]quinolizinone 13 is obtained. The reactions of α-methylhomophthalic anhydride (10) with 3 and the imidate 7 lead to the 1 (2H)-isoquinolinones 14 and 19, respectively, and with 4 to the 13-methyldibenzo[a,g]quinolizinone 15. The interaction of homophthalic anhydrides 1a, b with 3 aiming at the preparation of α-condensation products is investigated.
