  Synthesis and Properties of Shape-Persistent Macrocyclic Amphiphiles with Switchable Amphiphilic Portions

  摘要：

  The bidirectional- and convergent-type syntheses of functionalized kinked phenyl-ethynyl oligomers containing ethynyl end groups are described. Key steps in both approaches are the bromo-iodo selectivity of the Hagihara coupling and the possibility to deprotect acetylenes containing different silyl protective groups stepwise. Glaser coupling of the oligomeric bisacetylenes results in the corresponding macrocycles that contain polar and nonpolar side groups in a switchable arrangement.
