The preparation of cationic palladium (eta(3)-C3H5) complexes, possessing a
n enantiopure diphenylphosphinoferrocenyloxazoline unit, is described. Thes
e complexes were applied to the enantioselective amination of the test subs
trate, ethyl (2E)-1,3-diphenyl-prop-2-enyl carbonate, with benzylamine in m
oderate to high conversions with enantioselectivities of up to 72% for the
(S)-valinol derived oxazoline complex. Enantioselectivities of up to 37% we
re obtained for the (S)-tert-leucinol derived oxazoline complex. (C) 2000 E
