Highly efficient catalytic system for enantioselective Michael addition of aldehydes to nitroalkenes in water
(Chemical Equation Presented) Organocatalysis: A highly effective catalytic procedure for the Michael addition of aldehydes to nitroalkenes is achieved by combining the excellent asymmetric induction ability of o-TMS-protected diphenylprolinol compounds, the quick formation of enamines in the presence of benzoic acid, and the highly concentrated organic phase in water (see scheme; TMS=trimethylsilyl).
