✦ Synopsis

A series of new phosphorus-containing oxazoline ligands has been developed. The use of these ligands for asymmetric palladium camlysed allylic substitution of 1,3-diphenylprop-2enyLI-acetate 12 with the sodium salt of dimethylmalonale has been achieved with 90 -94% ee and 88 -99% yield.
