To achieve lowering of carbon dioxide, we examined the development of efficient organocatalysts that can use in ecofriendly sea water as a reaction solvent instead of an organic solvent. We have found that novel sulfonamide oraganocatalysts promote efficiently asymmetric aldol reactions in water or brine. The organocatalysts have been improved their catalytic activity by introduction of fluorous group. In addition, the fluorous oraganocatalysts can be easily recovered and reused.
