Synthesis of Fused Pyrimidines from Azole Amines and Their Biological Activity

European Journal of Organic Chemistry, Год журнала: 2024, Номер 27(43)

Опубликована: Авг. 3, 2024

Abstract Fused pyrimidines are a class of heterocyclic compounds that have gained considerable interest due to their extensive biological activities and potential applications in drug development. This review article aims provide comprehensive overview the latest synthetic approaches fused pyrimidines, including Michael reactions, multicomponent metal‐catalyzed photocatalytic peroxide‐mediated inverse electron demand Diels–Alder reactions. Furthermore, these compounds, such as ability combat cancer microbial infections, also discussed. summarizes existing literature on synthesis activity from 2020 2023. We hope this will inspire development more effective less toxic pyrimidine drugs with well‐designed structures.
