Fulleropyrrolidines have been very welcomed in a community of a fullerene science. But sometimes the synthesis ends up with disappointing yields of the products. In order to overcome the problem and to explore more environmentally benign method for synthesizing fullerene derivatives having various attachment on the surface of the fullerenes, a solid-phase synthesis is examined. We found that the dipolar cycloaddition of an azomethine ylide, i.e., 2-phenyl-N-benzylideneglycine methyl ester, supported on a Wang resin, proceeded feasibly with C 60 and the objective fulleropyrrolidines were afforded in good yields (>75%). The method is expected to be utilized with wide range of application and it is therefore able to provide a compound library of modified fullerenes which is hard to obtain by other methods employed so far.

Acidic Reagent

The acid lability of electron-rich N-benzylanilines has been exploited in a linker for the traceless solid-phase synthesis of benzimidazoles, 2-aminobenzimidazoles, quinoxalinones and tetrahydroquinoxalines. The target compound precursors were assembled on a solid-phase support derivatized with either a benzylamine or a benzhydrylamine linker. Exposure to an acidic reagent caused cleavage of the C(benzyl)-N(aniline) bond, releasing the product with only a hydrogen atom on the descending nitrogen. The Encore technique for directed sorting on SynPhase Lanterns has been developed and applied to combinatorial synthesis of generic drug discovery libraries.
