  摘要：

  Synthesis and initial in vitro evaluation of a novel series of phenyl oxazole derivatives are described. An SAR study of the novel dual-acting TRA/TSI agent has revealed that the lipophilicity of the oxazole amide substituents greatly influences the TRA activity but not the TSI. The chain length of the alkenoic acid side chain affects both TRA and TSI. The optimal chain length for the combined activities was found to be n = 4 (heptenoic acid). (C) 1998 Elsevier Science Ltd.

• Stereoselectivity in the Wittig reaction of phenyl 3-pyridyl ketones: Amide substituent effect on the preferential (E)-ollefin formation
  作者：Kumiko Takeuchi、Todd J. Kohn

  DOI：10.1016/s0040-4039(98)01194-0

  日期：1998.8

  A Wittig reaction of amide substituted phenyl 3-pyridyl ketones with “nonstabilized” phosphorus ylides which contain a carboxyl terminus preferentially forms (E)-olefin. The preference for this stereoselectivity stems from either hydrogen bonding or salt-bridge formation between the amide group and the carboxyl terminus during the oxaphosphetane intermediate formation.

  酰胺取代的苯基3-吡啶基酮与含有羧基末端的“不稳定的”磷酰化物的维蒂希反应优选形成（E）-烯烃。对于这种立体选择性的偏爱是由于在氧杂膦烷中间体的形成过程中，酰胺基团与羧基末端之间的氢键键合或盐桥形成。
