  摘要：

  A vinylogous dipyrrinone, its Ehrlich aldehyde condensate, and the vinylogous bilindione derived from the vinylogous dipyrrinone were prepared. Their structural aspects of tautomerism, configuration and conformation were derived by analysis of their H-1-NMR data. Selected physical properties were determined and are discussed.
