15 - 177The First Asymmetric Synthesis of α-Sulfanylphosphonates. —Carbanionic [2,3]-sigmatropic rearrangement of chiral dimenthylphosphonate(VI) gives α-mercapto γ-unsaturated phosphonate (VII) with good diastereos-electivity. The resulting thiol (VII) is easily converted to the thiolanes (VIII)and (IX). — (MARCHAND, PATRICE; GULEA, MIHAELA; MASSON,SERGE; SAQUET, MONIQUE; COLLIGNON, NOEL; Org.
