[反应:通过容易制备的(PhPYBOX)ErCl 3络合物催化HCN对腙的不对称加成,产率高,对映选择性好。这构成了腙的不对称催化氢氰化的第一个实例。
[reaction: see text] The asymmetric addition of HCN to hydrazones is catalyzed in high yield and good-to-excellent enantioselectivity by the easily prepared (PhPYBOX)ErCl3 complex. This constitutes the first example of asymmetric catalytic hydrocyanation of hydrazones.
