Preparative and structural chemistry of chiral 3-(diphenylphosphanyl)pyrrolidines and their palladium(II) complexes

The preparation of both enantiomers of 3-diphenylphosphanylpyrrolidine (2) and several N-substituted derivatives together with two Pd complexes of this ligand is reported. From L-malic acid and L-hydroxyproline both enantiomers of 3-hydroxypyrrolidine are prepared without any problems due to epimerization. KPPh2 in the presence of LiCl is shown to be the most effective reagent for the synthesis of 2. The reported X-ray structure determinations of PdI2 complexes show a rather rigid bicyclic hetero-norbornane skeleton. The flexibility of the other parts of the molecules is obvious in several polymorphs revealed by this method. This polymorphism is additionally investigated by a 31P-CP-MAS study. From solution 'H-, 13C- and 31P-NMR studies it is concluded that the bicyclic hetero-norbornane skeleton is retained in solution. VCH Verlagsgesellschaft mbH.
