Article abstract of DOI:10.1007/BF00505911

The reaction of o-haloamino derivatives of pyrimidine and pyridine with o-hydroxybenzaldehyde and its derivatives leads to the formation of tricyclic 1,4-oxazepine systems.Syntheses are reported for derivatives of pyrimido<4,5-b>- and pyrido<2,3-b>-1,4-be
