leads to the formation of the isoguinoline ring system incorporated in furo[3,4-c]isoquinolinediones -, resp. 13a-(chloromethyl)-8H- dibenzo[a,g]-quinolizine-8-one-13-carboxylic acids . The latter compounds were converted into furo[3′ 4′:9,9a]dibenzoquinolizinediones under basic conditions. NMR studies provided information concerning the relative configuration and the solution conformation of the various
