Synthetic efforts toward the preparation of rotaxane precursors based on phenylacetylene macrocycles (PAM) are described. The aim of this study was to determine the optimal structural parameters to prepare high-molecular-weight rotaxane precursors through a strategy involving two Sonogashira couplings to attach bulky blockers on the PAM core. PAMs with different sizes and functions were prepared and
描述了基于苯乙炔大环化合物 (PAM) 制备轮烷前体的合成工作。本研究的目的是通过涉及两个 Sonogashira 偶联的策略来确定制备高分子量轮烷前体的最佳结构参数,以在 PAM 核心上连接大块阻滞剂。制备了不同尺寸和功能的 PAM 并与不同的阻滞剂偶联,以评估所得结构是否采用类轮烷构象,其中刚性杆在 Sonogashira 偶联螺纹通过 PAM 后形成。
