    • In CD3CN, dehydropiperidines 25ab appeared, by NMR spectroscopic analysis, to exist in equilibrium with its corresponding five-membered dehydropyrrolidine through intermediacy of the corresponding aminal. Thus, despite extensive HPLC purification (Agilent Prep-C18 21.5 x 250 mm, 10-μm preparative column; 50% H2O/MeOH→30% H2O/MeOH; 1 mL min-1, tR=25.6 min, single band, the 1H NMR spectrum of 25ab revealed a multicomponent mixture. For other examples of such equilibria, see: a) K. C. Nicolaou, M. Nevalainen, M. Zak, S. Bulat, M. Bella, B. S. Safina, Angew. Chem. 2003, 115, 3540-3546;
