Facile Synthesis of Substituted Quinazolin‐4‐(3H)‐ones Using Low‐Valence Titanium Reagent

Abstract A short and facile synthesis of a series of 3‐aryl quinazolin‐4‐(3H)‐ones was accomplished in good yields via the intermolecular reductive coupling reaction of N‐aryl‐2‐nitrobenzamide and triethyl orthoformate promoted by TiCl4/Zn.
