Catalytic enantioselective cyanosilylation of ketones: improvement of enantioselectivity and catalyst turn-over by ligand tuning

✍ Yoshitaka Hamashima; Motomu Kanai; Masakatsu Shibasaki 📂 Article 📅 2001 🏛 Elsevier Science 🌐 French ⚖ 67 KB

Sterical and electronical tuning of the bifunctional catalyst 1 afforded the improved catalyst 2, which promoted the cyanosilylation of ketones with higher enantioselectivity as well as with improved catalyst turn-over with a factor of up to 10. Thus, chiral quaternary a-hydroxynitriles were obtaine
