Abstract
In this chapter, synthetic approaches to the preparation of seven-membered heterocycles such as azepines and benzodiazepines, oxazepines, thiazepines and dithiazepines are discussed. The data on the synthesis and biological properties of these heterocycles over the past 10–15 years are presented with an emphasis on one-pot preparation procedures. Two approaches are considered within the framework of one-stage synthesis of azepine derivatives – there are methods for recyclization of small and medium carbo-, oxa- or azacyclanes, as well as multicomponent heterocyclization reactions to prepare various compounds with azepine scaffolds.
