Synthesis of New Optically Active Bis- and Tris(phosphines)

Article abstract of DOI:10.1055/s-1989-27368

The synthesis of new optically active alkanediylbis- and alkanetriyltris(diphenylphosphines) is described.Easily accessible optically pure lactones and carboxylic acids are reduced to the alcohols, tosylated and reacted with lithium diphenylphosphide to give the corresponding phosphines.
