Abstract The conformation of 1‐phenyl‐1‐(1,2‐dimethyl‐5‐pyrrolyl)‐2‐(2‐methyl‐5‐benzoyl‐1‐pyrroly)ethanol, with characteristics of a molecular propeller, is stabilized by intramolecular hydrogen bonding as detected by 1 H NMR, NOE difference experiments, 2D NMR, COSY, 13 C NMR, HETCOR, HMBC and 1 H NMR variable‐temperature experiments.
