D. Enders et al., Diastereo- and enantioselective synthesis of alpha,beta-disubstituted gamma-nitro methyl sulfonates, CHEM COMMUN, (23), 2001, pp. 2498-2499
A novel asymmetric synthesis of highly enantioenriched homotaurine precurso
rs has been developed via diastereoselective Michael addition of lithiated
enantiopure sulfonates to nitroalkenes by using 1,2:5,6-di-O-isopropylidene
-alpha -D-allofuranose as chiral auxiliary.
