Application

Ethyl (S)-2-(trifluoromethylsulfonyloxy)propionate can be used:
  • In the synthesis of tetra-methylated analog of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTMA) based chelates for imaging applications.
  • As a substrate in the synthesis of α-silylated carboxyl compounds via Cu-catalyzed stereoinvertive nucleophilic silylation of α-triflyloxy esters.
