An efficient method for the synthesis of 1-(trifluoromethylsulfonamido)propan-2-yl benzoates is described, the products of the reaction were characterized by heteronuclear single quantum coherence spectroscopy (HSQC), heteronuclear multiple bond correlation (HMBC) and NMR experiments. The overall process began with the activation of the oxazoline ring by triflic anhydride, followed by the opening of
