  Synthesis of thio-heterocyclic analogues from Baylis–Hillman bromides as potent cyclooxygenase-2 inhibitors

  摘要：

  A series of thio-substituted pyrimidine, benzoxazole, benzothiazole and triazole analogues were synthesized from Baylis-Hillman bromides in a clean and efficient way. The synthesized twenty new compounds were subjected to in vitro COX-1 and COX-2 inhibitory activity. Majority of compounds found to be highly selective COX-2 inhibitor. Seven compounds (16e, 16f, 16k, 16l, 16m, 16r and 16s) displayed anti-inflammatory activity at micromolar concentrations with IC50 values for COX-2 inhibition ranging from 2.93 to 5.34 mu M compared to reference drug whose IC50 is 2.66 mu M. All these seven compounds had very little COX-1 inhibition property and thus are suitable candidates for anti-inflammatory drugs with less gastrointestinal side effect. (c) 2014 Elsevier Ltd.

• Préparation et étude de nouveaux dérivés organozinciques allyliques fonctionnels
  作者：François Lambert、Bernard Kirschleger、Jean Villiéras

  日期：1991.3

  Stable organozinc compounds derived from alkyl-3-alkyl-2-(bromomethyl)-proenoates have been prepared. NMR 13C, 1H and IR stidies show only one Z stereoisomer (no methylenic form) with a strong chelation between zinc and the carbonyl oxygen of the ester and solvated by only one solvent molecule. Hydrolysis can be achieved by two concurrent mechanisms with or without transposition.

  已经制备了衍生自烷基-3-烷基-2-（溴甲基）-烯酸酯的稳定的有机锌化合物。NMR 13 C，1 H和IR激发显示仅一种Z立体异构体（无亚甲基形式），在锌和酯的羰基氧之间具有很强的螯合性，仅被一个溶剂分子溶剂化。水解可以通过两种同时发生或不发生转座的机制来实现。

  日期：1991.3

  Stable organozinc compounds derived from alkyl 3-alkyl 2-(bromomethyl) propenoates reacted with ketones and aldehydes to give alpha-methylene gamma-butyrolactones in excellent yields. Different reaction parameters were studied and some transition states were proposed.
