This chapter covers the primary chemical literature of the title bi- and tricyclic ring systems cited in Chemical Abstracts Chemical Substance Indexes up to Volume 151 from Volume 144 between 2006 and 2009. Earlier literature data were systematically treated as primary subjects in Comprehensive Heterocyclic Chemistry series .
These ring systems occupy valuable parts of the chemical space for drug research, as most of their derivatives have drug-like properties and their outstanding representatives play an indispensable role in medicinal chemistry.
