Self‐assembled catalyst: A new kind of chiral supramolecular organocatalyst, self‐assembled from chiral amines and poly(alkene glycol)s, was developed. The resulting self‐assemblies were found to be highly efficient in the asymmetric catalysis of the unusual Diels–Alder reaction between cyclohexenones and nitrodienes, nitroenynes or nitroolefins, giving excellent chemo‐, regio‐ and enantioselectivities
自组装催化剂:开发了一种新型的手性超分子有机催化剂,由手性胺和聚(链烷二醇)自组装而成。结果表明,在环己烯酮与硝基二烯,硝基烯或硝基烯烃之间的异常Diels-Alder反应的不对称催化中,所得的自组装非常有效,具有出色的化学,区域和对映选择性(参见方案)。
