induced C(sp3)–Hamination of 2-aminobenzamides with ketones using TBAI as a catalyst was developed, and provided 2-benzoylquinazolin-4(3H)-onesundermetal-freeconditions. The reaction proceeded using the relatively low-toxicity methanol as the solvent, employed molecular oxygen as the ideal green oxidant in a simple undivided cell, and exhibited high atom economy. The mechanism of this C(sp3)–H amination
An efficient one-pot synthetic protocol has been proposed for the synthesis of luntonin F from easily available starting materials. Through a rational logical design, multifundamental reactions (iodination, Kornblum oxidation, and annulation) were assembled in one-pot. The developed approach can efficiently synthesize luntonin F and a diversity of analogues.
