Ab initio calcdations at the MP2/6-31G\*//HF/3-21G\* level have been carried out to study Eels-Alder reactions of 2-substituted-1,3-dienes with s u l h dioxide. The CH ... 0 electrostatic interaction detected in some of the transition structures located could be decisive in the control of the exo/en
