C-60 reacts thermally with azomethine ylides of glycine imines, in methyl ester and free acid form, bearing two alkylsulfanyl groups to give dihydro-pyrrolo[60]fullerene derivatives 2 and 5a, respectively, in a 1,3-dipolar cycloaddition reaction. The yields of products were found to depend strongly on acidic conditions applied and the size of the alkylsulfanyl substituent. Graphics. a: R=Me, b: R=Et, a R=Pro, d: R=i-Pro.
