Exocyclic Double Bond in Benzo-Fused Nitrogen Heterocycles: Methods of Introduction and Syntheses with Its Participation

Аннотация

The review summarizes methods for the synthesis of benzo-fused heterocyclic compounds containing a fairly stable exocyclic double bond in a saturated hetero- or polyheterocyclic fragment. Examples of using such compounds for the preparation of biologically active substances and heterocycles for other applications are given.
