Development of asymmetrically catalytic reactions produced only small amount of carbon dioxide using sea water as a reaction solvent

为了实现二氧化碳的降低，我们研究了高效有机催化剂的开发，这种催化剂可以在环保的海水中用作反应溶剂，而不是有机溶剂。我们发现新型磺胺有机催化剂能有效地促进水或盐水中的不对称羟醛缩合反应。通过引入含氟基团，有机催化剂的催化活性得到了提高。此外，含氟有机催化剂易于回收和重复使用。

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.
