  Diastereoselective Synthesis of γ-Amino-δ-hydroxy-α,α-difluorophosphonates: A Vehicle for Structure−activity Relationship Studies on SMA-7, a Potent Sphingomyelinase Inhibitor

  摘要：

  A highly diastereoselective synthesis of 2-amino alcohol derivatives bearing a difluoromethylphosphonothioate group at the 3-position was achieved through LiAlH(O-t-Bu)(3)-mediated reduction of the corresponding alpha-amino ketones. The phosphonothioate moiety of the product was readily converted into the corresponding phosphonate by oxidation with m-CPBA, followed by aqueous workup. The developed methods should be useful for SAR studies of SMA-7, a potent inhibitor of SMases.
