Anwendung

Catalyst for:

• Intermolecular conjugate addition of alcohols to unsaturated ketones and esters
• Preparation of β-amino carbonyl compounds by N-heterocyclic carbene-catalyzed enantioselective Mannich reactions of a-aryloxyacetaldehydes with imines
• Asymmetric synthesis of cyclopentenes from allyl diketones by carbene-catalyzed intramolecular aldol reaction, lactonization, and carbon dioxide expulsion
• Preparation of esters via tandem oxidation of allylic/benzylic/propargyl alcohols or aldehyde
