Analyse conformationnelle a l'aide de la notation des angles de torsion X: Interprétation de la régiosélectivité d'ouverture des époxydes de composés bicycliques incorporant des cycles petits et moyens

Using the dynamic method of conformational analysis through the implementation of the torsion angle notation and applying the rules of distortion compatibility at the junction of fused rings, permits the interpretation or prediction of the regioselective opening of epoxides and analogous three-membered heterocycles of the halonium type fused to small and medium rings.
