Bi(TFA)3–[nbp]FeCl4: a new, efficient and reusable promoter system for the synthesis of 4(3H)-quinazolinone derivatives
摘要:
4(3H)-Quinazolinones have been synthesized in high to excellent yields through the one-pot condensation of anthranilic acid, trimethyl orthoformate and primary amines in the presence of 5 mol % of Bi(TFA)(3) immobilized on [nbp]FeCl4 as a room temperature ionic liquid.
