An impurity and a partial overlap of one resonance with the solvent led to incorrect peak assignments in the 13C NMR spectrum for compound 7. A revised version of the Supporting Information with the correct data and spectra is included. We thank Prof. Andrei Kutateladze (University of Denver) for his help in identifying this inaccuracy.
