Preparation of 2,4,5-trisubstituted thiazole derivatives via a new solid-phase synthetic route has been conducted in this study. The synthetic route begins with the synthesis of a core skeleton 2,4-diamino(thiazol-5-yl)-substituted phenylmethanone resin obtained through a cyclization reaction with a carbamimidothioate linker. The core skeleton was substituted with diverse building blocks such as amines
在这项研究中,已经通过新的固相合成路线制备了2,4,5-三取代的噻唑衍生物。合成途径开始于合成核心骨架的2,4-二氨基(噻唑-5-基)取代的苯基甲酮树脂,该树脂是通过与氨基甲硫基氨基甲酸酯连接基的环化反应获得的。核心骨架被各种结构单元取代,例如胺,烷基卤化物和酰氯。通过TFA / CH 2 Cl 2裂解混合物从固体支持物裂解产物。总体而言,该策略允许将三点多样性并入噻唑环系统中,并具有良好的总收率(李T; 等。J.梳 化学 2009年,11(2),288-293)。最后,通过计算理化性质,2,4,5-三取代噻唑衍生物库显示出口服生物利用度。
