Abstract
Quinazoline and its oxidized analogs, quinazolinones, are privileged motifs due to their frequent occurrence in natural products and bioactive compounds. Therefore, the development of efficient methods for the synthesis of quinazoline derivatives has been a significant research objective in organic and medicinal chemistry. Although conventional syntheses of quinazoline derivatives generally depend on acid/base-mediated condensation reactions, hetero Diels-Alder reactions, aza-Wittig reactions, etc., modern approaches that utilize transition-metal catalysts have also been developed, enabling streamlined construction of quinazoline frameworks. In this chapter, Cu-mediated methods for the construction of quinazolines and related benzodiazines are surveyed. In addition, Cu-mediated modifications of quinazoline and quinoxaline scaffolds are discussed briefly.
