Abstract

o-Benzoquinone reacts with norbornadiene to yield a mixture of exo and endo stereoisomeric bridged α-diones which are condensed with vic-diamines (o-phenylenediamines, 5,6-diamino uracil or 5,6-diaminophenanthroline) to produce the corresponding heterocyclic fused-norbornenes; other rod or angled molrac α-dione blocks and heterocycles derived therefrom are described which open new avenues for macrostructure development via block coupling protocols.
