Beschreibung

Anwendung

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.
