Abstract

Azaheterocycles comprise relevant target structures within organic chemistry due to the broad diversity of biological activities associated with these scaffolds. In this review, the most important recent procedures for the preparation of functionalized six-membered azaheterocyclic compounds by ring transformation of β-lactams are summarized and discussed.

Keywords: β-lactams, ring transformation, six-membered azaheterocycles, morpholines, piperidines, oxazinanes, piperazines
