Benzoheteropines with fused pyrrole, furan, and thiophene rings, of great
interest because of their biological activity, are surveyed by Dr. D.O. Tymoshenko
of the Albany Molecular Research Institute, New York. These compound classes
were considered in both the first and second editions of Comprehensive
Heterocyclic Chemistry as part of a host of related multi-atom heterocyclic
systems. Other specialized reviews have appeared. However, the present survey
is the first comprehensive treatment.
The synthesis of hetero annulated azocines is treated by L.G. Voskressensky,
L.N Kulikova, T.N. Borisova, A.V. Varlamov (all of Russian Peoples Friendship
University, Moscow). While azocino-[4,3-b]indoles have been studied because
many alkaloids contain this ring system; the present survey covers all six
isomeric azocinoindoles.
