摘要:
Asymmetric catalytic allylic amination of 1,3-diphenylallyl acetate with dipropylamine in an ionic liquid, 1-butyl-2,3-dimethylimidazolium tetrafluoroborate, and in THF and CH2Cl2 in the presence of palladium complexes of P-monodentate phosphite and phosphoramidite derivatives of S-1,1'-bis-2-naphthol was carried Out. This gave a product with ee of up to 65%. The level of asymmetric induction is retained after three catalyst cycles.
