Abstract
A fluorous (S)-pyrrolidine sulfonamide organocatalyst promotes highly enantio- and diastereoselective Michael addition reactions of ketones and aldehydes with nitroolefins in water. The organocatalyst is conveniently recovered from the reaction mixtures by fluorous solid-phase extraction and can be reused.
