摘要
The synthesis of (S)-1,2-bis(diphenylphosphino)butane-4-ol 1 an acyclic analogue of hydroxy norphos is described, starting from L-ascorbic acid. Problems which arose during the cleavage of OH-protective groups in the presence of phosphino groups are discussed. The hydrogenation properties of the catalyst derived from the new ligand are compared with those obtained with hydroxy norphos.(1)
