coordination diastereomer according to their NMR spectra (−5 to −20 °C). This stereoselective coordination results in stereoselectiveelectrophilic addition at the uncoordinated β carbon (C3) when the complexes are treated with trifluoromethanesulfonic acid (HOTf), methyl triflate, or dimethoxymethane. These stereoselectivereactions at C3 are a direct result of differentiation of the pyrrole enantiofaces
