Abstract:

Cinchona alkaloid derivatives as organocatalysts were applied in asymmetric Michael addition reaction of anthrone with various trans-β-nitroolefins. Solvent, temperature and catalyst loading were screened. The optimized conditions are using toluene as the solvent with a 5%(molar fraction) loading of catalyst 1b at room temperature. The products are obtained in 91%~99% yield with up to 95%ee.

 

Key words: Cinchona alkaloid derivative, organocatalysis, asymmetric Michael addition, anthrone, β-nitroolefins
