The synthesis of two versatile building blocks for supramolecular anion binding motifs, 5-(N-Boc-guanidinocarbonyl)-1H-pyrrole-2-carboxylic acid (1) and 5-(N-Cbz-guanidinocarbonyl)-1H-pyrrole-2-carboxylic acid (2) is reported. Using these building blocks, a guanidiniocarbonyl-pyrrole anion binding site can easily be introduced into more complex molecules by using standard amide coupling conditions
超分子阴离子结合基序的两种通用构件的合成,5-(N-Boc-guanidinocarbonyl)-1H-pyrrole-2-carboxy acid (1) 和 5-(N-Cbz-guanidinocarbonyl)-1H-pyrrole-2报道了-羧酸(2)。使用这些构建块,可以通过使用标准酰胺偶联条件将胍基羰基-吡咯阴离子结合位点轻松引入更复杂的分子中。两种合成都可以在多克规模上进行。产品以纯净形式获得,可以作为固体储存而不会分解。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
