Iron(III) Chloride Catalyzed Synthesis of Functionalized Spiropyrimidines
摘要:
Potentially bioactive pyrimidine-annulated spiroheterocyclic compounds are synthesized in good to excellent yields using readily available, cheap and environmentally friendly iron(III) chloride (FeCl3) as the catalyst. The process is straightforward and provides a diverse range of spiropyrimidine derivatives via the 5-endo-dig mode of cyclization, starting from simple and easily available starting materials.
