Glutaconic anhydride (9) reacts with N-substituted benzimidoyl chlorides 3 to give the corresponding (Z)-3-pyrandiones 12, whereas with 1-chloroisoquinoline (4) the benzoquinolizinone 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-methyldibenzoquinolizinone 15.The interaction of homophthalic anhydrides 1a, b with 3 aiming at the preparation of α-condensation products is investigated.
