Resumen

Reaction of 2-aminophenol and 2-aminothiophenol with 1-phenyl-1,2-propanedione yields a mixture of both possible isomeric benzo[1,4]oxazines and benzothiazolines which were characterized by NMR spectroscopy. In addition, the structures for 3-methyl-2-phenyl-2H-benzo[1,4]-oxazin-2-oI and 1-(2-phenyl-2,3-dihydro-benzothiazol-2-yl)-ethanone were established by X-ray diffraction analysis.
