  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 diastereoselective Michael addition of lithiated enantiopure sulfonates to nitroalkenes is described. High asymmetric inductions were obtained by using 1,2:5,6-di-O-isopropylideneα-D-allofuranose as a cheap and easilyavailable chiral auxiliary. Racemization-free cleavage of the auxiliary led to α,β-disubstituted γ-nitro methyl sulfonates. A change of the cleavage conditions resulted in α,β-disubstituted

  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.

  日期：2009.11

  The first asymmetric synthesis of alpha,beta-disubstituted gamma-phosphono sulfonates is reported. The key step is the Michael addition of a lithiated enantiopure sulfonate bearing an inexpensive chiral sugar auxiliary to alpha,beta-unsaturated phosphonates in good diastereoselectivities. After chromatographic purification, the cleavage of the chiral sugar auxiliary proceeds without any epimerization or racemization to form the corresponding isopropyl sulfonate in very good overall yield (75%) and excellent diastereomeric and enantiomeric excess (de, ee >= 95%).
