  • Synthesis of 4H-3,1-Benzoxazines by the Reaction of o-(N-Acylamino)benzyl Alcohols with DAST
    作者:Takehiko Nishio、Yukiko Kurokawa、Yoshiya Narasaki、Tatsuhiro Tokunaga
    DOI:10.3987/com-05-s(t)22
    日期:——
    The treatment of o-(N-acylamino)benzyl alcohols (1) with DAST afforded the dehydrative cyclization product, 4H-3,1-benzoxazines (4) and the hydroxy replacement product, o-(N-acylamino)benzyl fluorides (5). The yields of benzoxazines (4) and fluorides (5) depend on the substituents at alpha-position and acyl groups. The treatment of alpha,alpha-diaryl-o-(N-acylamino)benzyl alcohols (1a-c) with DAST yielded benzoxazines (4a-c) exclusively, while that of alpha-monosubstituted o-(N-acylamino)benzyl alcohols (Id-k) with DAST yielded benzoxazines (4d-k) and fluorides (5d-k). In the reaction of o-(N-acylamino)benzyl alcohol (11) with DAST, the formation of fluoride (51) became predominant and that of benzoxazine (41) was suppressed almost completely.
  • A Novel o-Iminophenyl Anion Route to Heterocycles and Ortho-Substituted Anilines
    作者:Alan R. Katritzky、Guifen Zhang、Jinlong Jiang、Peter J. Steel
    DOI:10.1021/jo00128a040
    日期:1995.11
    Ring opening of lithio derivatives of N-(alpha-alkoxyalkyl)benzotriazoles 9 and 22 and subsequent extrusion of nitrogen at -78 degrees C gave novel o-iminophenyl anions which enable synthetically useful preparations of ortho-substituted anilines (19 and 25) and of benzoheterocycles (14, 20, 21, 24, and 26).
