This paper outlines the synthesis of a number of structural analogs of 3-[(4,6-diphenoxy-1,3,5-triazin-2-yl)amino]benzoic acid which represent compounds with potential cardiogenetic activity. A one-pot protocol was developed for swift functionalization of the 1,3,5-triazine core without the need of isolating intermediates. The developed route starts from readily available 2,4,6-trichloro-1,3,5-triazine, displacing the chlorine atoms sequentially by aryloxy, arylamino, or arylthio moieties to enable access to molecules with three different substituents of this type in good yields. To facilitate purification, -butyl, methyl, and ethyl ester derivatives of the target compounds were initially synthesized. The -butyl esters could be readily hydrolyzed to the desired compounds, while reduction of the methyl and ethyl esters gave the corresponding benzylic alcohols in high yields, thereby expanding the substrate scope for future relevant cell assays.
本文概述了一系列3-[(4,6-二苯氧基-1,3,5-三嗪-2-基)氨基]苯甲酸结构类似物的合成,这些类似物代表具有潜在心脏发生活性的化合物。开发了一种一锅法方案,用于1,3,5-三嗪核心的快速官能化,无需分离中间体。所开发的路线从容易获得的2,4,6-三氯-1,3,5-三嗪开始,依次用芳氧基、芳氨基或芳硫基部分取代氯原子,从而能够以良好的产率获得具有三种不同此类取代基的分子。为便于纯化,最初合成了目标化合物的叔丁酯、甲酯和乙酯衍生物。叔丁酯可容易地水解为所需化合物,而甲酯和乙酯的还原则以高产率得到相应的苄醇,从而扩大了未来相关细胞试验的底物范围。
