Application

Catalyst for:
  • Enantioselective construction of beta-quaternary carbons via conjugate addition reactions
  • Generation of reactive enolates
  • Regioselective / stereoselective conjugate addition of cyanide to enones
  • Strecker reactions
  • Asymmetric ring-opening of meso-aziridines
Catalyst used in a ring opening of meso-aziridines with trimethylsilyl azide.
In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.

Yuhei Fukuta et al.
Journal of the American Chemical Society, 128(19), 6312-6313 (2006-05-11)
An asymmetric ring-opening reaction of meso-aziridines with TMSN3 was developed using a catalyst prepared from Y(OiPr)3 and chiral ligand 2 in a 1:2 ratio. Excellent enantioselectivity was realized from a wide range of substrates with a practical catalyst loading. The
