  • 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.
  • Sulfur-containing Heterocycles Derived by Reaction of N-Thioacylamino Alcohols with Lawesson’s Reagent and Saponification of N-Thioacylamino Esters
    作者:Takehiko Nishio、Hiroshi Sekiguchi
    DOI:10.3987/com-02-s(m)9
    日期:——
    The treatment of 2-N-thioacylamino alcohols (1) with Lawesson's reagent [LR: 2,4-bis(p-methoxyphenyl)-1,3,2,4-dithiaphosphetane 2,4-disulfide] afforded the sulfur-containing heterocycles, 1,3-thiazolines (2) in moderate to good yields, exclusively. The saponification of N-thioacylamino esters (4), which were prepared by the thionation of N-acylamino esters (3) with LR, with K2CO3 gave 3,1-benezothiazines (5) and 3,1-benzoxazines (6).
