A new family of chiralsurfactants derived from N‐methylephedrine possessing different counter‐ions (Br−, , (S)‐(−)‐lactate−) is easily prepared and used as efficient protective agents of rhodium(0) nanoparticles. The resulting, well‐characterized materials prove to be active catalysts in the hydrogenation of ethylpyruvate in neatwater, with modest enantiomeric excesses.
