摘要: Gold nanoparticles functionalised with a valine-derived formamide have been developed as effective homogenous catalysts for the asymmetric reduction of ketimine 1 trichlorosilane (≤84% ee) in toluene. This methodology both simplifies recovery catalyst and its separation from product, can be readily removed subsequently recycled by precipitation reaction mixture.
