A new family of chiral surfactants derived from N-methylephedrine possessing different counter-ions (Br, equation image, (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 neat water, with modest enantiomeric excesses.
