N-Boc-protected monomer for the synthesis of oligourea foldamers containing the (1H-imidazolyl-4yl)methyl side chain of histidine, has been prepared in seven steps from Trt-His(τ-Trt)-OMe. This protecting group combination on histidine was found to be critical to ensure efficient access to the requisite activated building block. This new derivative, suitable for solid phase synthesis, expands the current arsenal
从Trt-His(τ-Trt)-OMe经过七个步骤制备了一种新的N -Boc保护的单体,用于合成含有组氨酸的(1 H-咪唑基-4基)甲基侧链的寡聚尿烷折叠剂。发现在组氨酸上的该保护基组合对于确保有效获得必需的活化构件至关重要。这种适用于固相合成的新衍生物扩大了具有蛋白原性侧链的结构单元的现有武库,可用于设计拟肽寡核苷酸折叠剂。
