Stereoselective Alkylation of Arenes with Threonine Trifluoromethanesulfonates

N-Phthaloylthreonine and -allothreonine methyl esters 3 react with trifluoromethanesulfonic anhydride / pyridine in dichloromethane to give threonine and allothreonine, respectively, trifluoromethanesulfonates 4 in quantitative yields.Arenes can be alkyla
