Abstract
We describe the two-step sequence for transforming enaminothioenone 1 to the planar semicyclic amidine 2 via an ylidenemalononitrile enamine intermediate, leading to the formation of the new π-conjugated heterocyclic system 5,6,10b-triazaacephenanthrylene, structurally related to the naturally occurring alkaloid aristolactams.
