The novel fluorous organocatalyst bearing a diaminomethylenemalononitrile motif is prepared. The fluorous organocatalyst efficiently promotes asymmetric conjugate additions of ketones to nitroalkenes and results in high yields of these addition products with excellent enantioselectivities under solvent-free conditions.
制备了带有二氨基亚甲基丙二腈基序的新型氟代有机催化剂。该氟代有机催化剂能有效促进酮与硝基烯烃的不对称共轭加成反应,在无溶剂条件下,这些加成产物能以高收率和优异的对映选择性生成。
