Efficient asymmetric synthesis of α-alkylated benzylic methyl sulfonates

The first highly efficient auxiliary-controlled synthesis of various α-substituted sulfonic acid derivatives is described. Alkyl or aryl halides were reacted with lithiated benzylic sulfonic esters bearing 1,2:5,6-di-O-isopropylidene-α-d-allofuranose as a

Asymmetric Synthesis of α,γ-Substituted γ-Sultones via Allylation of Chiral Lithiated Sulfonates

The first auxiliary controlled asymmetric synthesis of enantiopure α,γ-substituted γ-sultones via α-allylation of lithiated sulfonates by using 1,2:5,6-di-O-isopropylidene-α -D-allofuranose as chiral auxiliary is described. The high asymmetric inductions

A practical approach towards the asymmetric synthesis of α,γ-substituted γ-sultones

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-isopro
