摘要：
The first second-generation designer Ru(II) catalyst 1b featuring an enantiopure N,C-(N-ethylene-N-methyl-sulfamoyI)-tethered (DPEN-k(2)N,N)/n(6)toluene hybrid ligand Is introduced. Using an SIC 1000 in HCO2H Et3N 5:2 transfer hydrogenation medium, secondary 1-naphthyl alcohols are obtained in up to >99.9% ee under mild conditions. Mechanistic factors are discussed.
