RT info:eu-repo/semantics/article T1 Recyclable Chiral Bifunctional Thioureas Derived from [60]Fullerene and Their Use as Highly Efficient Organocatalysts for the Asymmetric Nitro-Michael Reaction A1 Andrés García, José María A1 González Pérez, Miguel A1 Maestro Fernández, Alicia A1 Naharro, Daniel A1 Pedrosa Sáez, Rafael K1 Catálisis K1 Química orgánica AB Three novel fullerothioureas derived from natural valine, phenylalanine, and tert-leucine have been prepared by Prato's reaction of [60]fullerene and the corresponding aldehydes. These hybrids have been used as organocatalysts in a typical stereoselective nitro-Michael addition reaction under homogeneous and neat conditions. The catalysts are easily recoverable by filtration, and are recyclable for at least five times. The addition products were obtained in excellent yields and stereoselectivities by using catalyst loadings of as low as 0.5 mol-%.
