Enders, Dieter,Adelbrecht, Jean-Claude,Harnying, Wacharee

, p. 2962 - 2968 (2007/10/03)

An efficient asymmetric synthesis of substituted β-alkoxycarbonyl sulfonates is described. Enantiopure α-substituted β-alkoxycarbonyl sulfonates can be obtained via α-alkylation of metalated sulfonates bearing 1,2:5,6-di-O-isopropylidene-α-D-allofuranose
