applications. Due to steric hindrance, these propeller-shaped molecules display slow interconversion between their two enantiomeric conformations (right-handed and left-handed propeller conformations). Syntheses and HPLC resolutions carried out on a chiral stationary phase have been achieved. The influence of the hybridization of the central carbon atom as well as the para substitutient on the conformational
