Tetrasubstituted thieno[3,2‐b]pyridin‐5(4H)‐one derivatives were selected as a highly functionalized heterocyclic scaffold for a multisite‐specific tagging process utilizing a previously devised fluorous fluorescent tag system. A suitable synthetic method was established for the 7‐alkoxy‐2,4,6‐trisubstituted‐thieno[3,2‐b]pyridin‐5(4H)‐one derivatives, and incorporating t‐butoxycarbonyl‐functionalized
使用先前设计的荧光标记系统,选择了四取代的噻吩并[3,2 - b ]吡啶5-5 (4 H)-one衍生物作为高度功能化的杂环支架,用于多位点特异性标记过程。建立了合适的合成方法用于7-烷氧基-2,4,6-三取代-噻吩并[3,2 - b ]吡啶5-5 (4 H)-one衍生物,并将叔丁氧羰基官能化的结构单元并入反应序列产生的前体可用于标记过程。经过一系列反应,包括t- Bu脱保护/ N,通过氟固相萃取有助于标记的目标化合物的纯化-羟基琥珀酰亚胺酯的形成/酰胺化。
