Abstract


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