Asymmetric synthesis of chiral ferrocenyl fulleropyrrolidines as potential building blocks for new materials

Asymmetric [3+2] cycloaddition of chiral ferrocenyl substituted azomethine ylides to C60 leads to the corresponding fulleropyrrolidines with high diastereoselectivities. This methodology has been applied to the preparation of a C2-symmetric enantiopure fullerene dimer.
