    • The β-hydroxyketone 3a is formed during the reaction, not during the subsequent workup. For example, upon a long-term storage of 2a, there was no change in the spectral integrity or in its TLC profile.

    • Typical side products formed at an early stage of the reaction and showed multiple non-polar spots in TLC, which could not be unambiguously identified. A similar observation was made by Gagosz: Gagosz, F. Org. Lett. 2005, 7, 4129.
