使用零价钯络合物和SEGPHOS或MeOBlPHEP配体的组合可以有效地进行2,3-丙二烯基磷酸酯与氮亲核试剂如胺、羟胺和酰亚胺的不对称胺化,从而提供相应的光学活性1-胺化衍生物,其对映体过量高达97%ee。
[GRAPHICS]Asymmetric amination of 2,3-allenyl phosphates with nitrogen nucleophiles such as amines, hydroxylamines, and imides can be performed efficiently using a combination of zerovalent palladium complexes and SEGPHOS or MeOBlPHEP ligand, affording the corresponding optically active 1-aminated derivatives with enantiomeric excess of up to 97% ee.
