Highly functionalized phospholanes 15, 17, and 26 and the corresponding diastereomers in which the configurations of the phospholane carbon-2 and carbon-5 are inverted can be readily prepared from d-mannitol by displacement of the appropriate dimesylate or cyclic sulfate with dilithiumphosphide reagents. The diols from which these ligands are prepared can also be converted into diarylphosphinite ligands
