The new PN ligands 5, 6 and 7 were prepared by Schiff base condensation of 2-formylphenyl(diphenyl)phosphine (1) with the optically active amines (R)-(-)-2-aminobutanol (2), (S)-(+)-2-aminobutanol (3) and (1S,2S)-2-amino-1-phenyl-1,3-propanediol (4). These new ligands were used in the Pd catalysed allylation of 1,5-dimethylbarbituric acid with allylacetate. 5-Allyl-1,5-dimethylbarbituric acid was obtained with an optical induction of up to 12.7% ee.
