Highly Efficient One-Pot Synthesis of 2-Substituted Quinazolines and 4H-Benzo[d][1,3]oxazines via Cross Dehydrogenative Coupling using Sodium Hypochlorite
This communication describes a catalyst-free synthesis of 2-substituted quinazolines and 4H-benzo[d][1,3]oxazines using commericially available sodium hypochlorite as oxidant. Operational simplicity, mild reaction conditions and the ability to construct structurally diverse 2-quinazolines and 2-substituted 4H-benzo[d][1,3]oxazines by this method render it to be a practical alternative for the synthesis of these heterocycles.
