Abstract

We have demonstrated a facile synthesis of diversely substituted quinazolines and 3,4-dihydroquinazolines through the o-iodoxybenzoic acid (IBX) mediated tandem reaction of readily available o-aminobenzylamine and aldehydes. The yield of the reactions generally ranged from 70% to 95%. This mild protocol provides an efficient strategy toward the synthesis of these classes of heterocycles.
