Functionalized N,O-bridged calix[1]arene[4]pyridines, first examples of the odd-numbered heterocalixaromatics containing mixed heteroatom bridges and mixed aromatic units, have been synthesized from the Pd2(dba)3/dppp-catalyzed 2+3 macrocyclic fragment coupling reaction between readily available staring materials. These novel macrocyclic compounds, which adopted distorted 1,3-alternate conformation
由Pd 2(dba)3 / dppp催化的2+ 3大环片段之间容易发生凝结物的偶合反应。这些新颖的固态大环化合物采用扭曲的1,3-交替构象,是强大的宿主分子,能够与富勒烯C 60在溶液中形成1:1络合物,结合常数高达49,494 M -1。
