A novel type of bidentate hydrogen bond donor catalysts based on (thio)phosphorodiamides catalophore has been developed for the asymmetric Michael addition of 2-hydroxy-1,4-naphthoquione to nitroolefins, affording the corresponding adducts in high yields with excellent level of enantioselectivities (97- >99% ee).
开发了一种新型的基于(硫)磷酰胺的双齿氢键供体催化剂作为手性载体,用于 2-羟基-1,4-萘醌与硝基烯烃的不对称迈克尔加成反应,以高产率和优异的对映选择性(97- >99%ee)得到相应的加合物。
