二氨基亚甲基丙二腈有机催化剂有效催化α-氰基酮与乙烯基酮的不对称共轭加成,得到相应的1,5-二羰基化合物,该化合物具有高对映选择性的全碳四元立体中心。该报告是使用有机催化剂将 α-氰基酮与乙烯基酮进行不对称共轭加成的第一个例子。
A diaminomethylenemalononitrile organocatalyst efficiently catalyzed the asymmetric conjugate addition of α-cyanoketones to vinyl ketones to give the corresponding 1,5-dicarbonyl compounds, which bear an all-carbon quaternary stereogenic center with high enantioselectivities. This report is the first example of the asymmetric conjugate addition of α-cyanoketones to vinyl ketones using an organocatalyst.
