In this paper a general procedure for the introduction of pyridone moiety was developed, using a Friedländer reaction, for post-modification of ready-made BODIPY core, from which three pyridone-fused BODIPYs 1, 2 and 3 were generated. This method is complementary to the classical method for obtaining aromatic ring-fused BODIPYs, which begins with the condensation of the corresponding aromatic ring-fused pyrroles. These pyridone-fused BODIPYs are distinctive, possessing favorable photophysical characteristics with strong absorption, high bright orange fluorescence and easy reduction due to the electron-withdrawing effect of the fused pyridone moiety. More important, these BODIPYs bear reactive functions which are applicable in proteins labeling by bioorthogonal chemical reactions.
本文开发了一种引入吡啶酮分子的通用程序,利用弗里德兰德反应对现成的 BODIPY 核心进行后修饰,从中生成了三种吡啶酮融合的 BODIPY 1、2 和 3。这种方法是对传统的芳香环融合 BODIPYs 获得方法的补充,传统的方法首先是缩合相应的芳香环融合吡咯。这些吡啶酮融合的 BODIPY 具有独特的光物理特性,吸收强、亮橙色荧光高,而且由于融合的吡啶酮分子的吸电子效应而易于还原。更重要的是,这些 BODIPY 具有反应功能,可用于通过生物正交化学反应标记蛋白质。
