  A Practical Approach Towards the Asymmetric Synthesis of α,γ-Substituted γ-Sultones

  摘要：

  本文描述了通过α-烯丙基化手性磺酸盐对对映纯的α,γ-取代的γ-琥珀酸内酯进行首次辅助控制合成。通过我们之前描述的辅助1,2:5,6-二-O-异亚丙基-α-d-呋喃糖（de≥98%），实现了α-烯丙基化的高不对称诱导。辅助剂的裂解和磺酸中间体的连续非对映选择性环闭合，以高选择性（de, ee≥98%）和良好至极佳的产率（52-90%）获得了标题化合物。对映纯的α,γ-取代的γ-琥珀酸内酯是与各种亲核试剂反应的有趣中间体。

  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.

  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.
