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.
