The synthesis of T-symmetrical [6:0]-hexakis adducts of C60 bearing enantiopure cyclo-monomalonate addends equipped with 1,2-glycol groups masked as isopropylidene acetals is presented. The deprotection of the acetals afforded functional fullerene building blocks bearing six 1,2-glycol moieties in an octahedral geometry as connection sites with appropriate linear organic spacers targeting 3D chiral
提出了带有被掩蔽为异亚丙基缩醛的1,2-乙二醇基团的C 60带有对映体纯的环-monomalonate加成物的T-对称[6:0]-己基加合物的合成。乙缩醛的脱保护得到功能性富勒烯结构单元,其具有八面体几何形状的六个1,2-二醇部分作为连接位点,并带有适当的线性有机间隔物,这些间隔物以带有立方体结构单元的3D手性扩展网络为目标。对实验结果的评估表明,该化合物可合成六官能加合物(-)- 9,该羰基带有六个同手性C12环-monomalonate加成物。
