  Efficient asymmetric synthesis of α-alkylated benzylic methyl sulfonates

  摘要：

  The first highly efficient auxiliary-controlled synthesis of various alpha-substituted sulfortic acid derivatives is described. Alkyl or aryl halides were reacted with lithiated benzylic sulfortic esters bearing 1,2:5,6-di-O-isopropylidene-alpha-D-allofuranose as a removable enantiopure alcohol auxiliary to give the alkylated products in excellent diastereomeric excesses. The racemization-free cleavage conditions provided highly enantioenriched sulfonic acid derivatives (ee >= 98%). (c) 2005 Elsevier Ltd. All rights reserved.

  A highly efficient asymmetric synthesis of α,γ-substituted γ-amino sulfonates via diastereoselective ring-opening of enantiopure α,γ-substituted γ-sultones with inversion of configuration at the attacked γ-carbon is described. In the key step sodium azide is used as the nucleophilic nitrogen source. Secondary and tertiary γ-amino sulfonates were synthesized in very good yields and excellent diastereo- and enantiomeric excesses (de, ee ≥98%).

  The first auxiliary controlled synthesis of enantiopure α,γ-substituted γ-sultones via α-allylated chiral sulfonates is described. The high asymmetric inductions of the α-allylations were reached with our previously described auxiliary 1,2:5,6-di-O-isopropylidene-α-d-allofuranose (de≥98%). Cleavage of the auxiliary and successive diastereoselective ring closure of the sulfonic acid intermediates led to the title compounds in high selectivities (de, ee≥98%) and good to excellent yields (52-90%). Enantiopure α,γ-substituted γ-sultones are interesting intermediates in the reaction with various nucleophiles.

  The hydrolysis of enantiopure α,γ-substituted γ-sultones with water under mild conditions leads to α,γ-substituted γ-hydroxy methyl sulfonates in very good yields and excellent diastereo- and enantiomeric excesses (de, ee ≥ 98%). The reaction proceeds via a SN2 mechanism with inversion of configuration at the attacked γ-carbon atom whose absolute configuration was established by X-ray crystallography.
