摘要:
A ferrocene-derived P,N-heterodonor ligand was effectively used in a Cu(OAc)2 center dot H2O-catalysed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with maleate derivatives, affording cycloadducts with high yields (up to 96%), diastereoselectivities (>99 dr), and enantioselectivities (up to 99% ee).
