A Cu(I)-catalyzed asymmetric diamination for a variety of conjugated dienes and a triene with encouraging ee's has been effectively achieved using (R)-DTBM-SEGPHOS as a chiral ligand and di- tert-butyldiaziridinone as the nitrogen source.
使用(R)-DTBM-SEGPHOS作为手性配体、二叔丁基二氮杂环丁烷作为氮源,已有效地实现了铜(I)催化的多种共轭二烯和一种三烯的不对称双胺化反应,对映体过量值令人鼓舞。
