Easy access to N-aryl, N-heteroarylbenzoxazolinones and 4-aza analogues via Diels-Alder cycloaddition reactions

An improved method for the synthesis of N-aryl, N- heteroarylbenzoxazolinones and their 4-aza analogues is described. The process involves the Diels-Alder cycloaddition of benzoxazinic or pyridoxazinic dienic systems with dienophiles as a key step.
