A new class of ionic liquid supported (ILS) (S)-pyrrolidine sulfonamide organocatalyst has been developed and shown to be a very effective catalyst for the asymmetric Michael addition reactions of ketones and aldehyde to nitroolefins with high enantio- and diastereoselectivities. This ILS organocatalyst is also easily recycled and could be reused at least five times without significant loss of its ability to affect the outcome of the asymmetric reactions.
一类新型的离子液体负载（ILS）（S）-吡咯烷磺酰胺有机催化剂已被开发出来，并被证明是一种非常有效的催化剂，可用于酮和醛与硝基烯烃的不对称迈克尔加成反应，具有高对映选择性和非对映选择性。这种ILS有机催化剂也易于回收，并且可以重复使用至少五次，而不会显著丧失其影响不对称反应结果的能力。
