A) Action of different catalysts (at 1.5 mM total amine) on methodol (15 mM) at 20 °C in CDCl3 using 1H NMR. Sequences 6, 8 and 9 are fit to burst kinetics, Et3N and BuNH2 to a linear model. The data points for heptamer 8 correspond to the average from two independent measurements. B) Reaction rates obtained from the fit in (A)—error bars depict the error of the fit. C) Dependence of velocity on [methodol] (2–30 mM) using foldamer 8 at 20 °C in CHCl3 monitored by HPLC.
