| Abstract: | Investigation on the transition structure of the ene reaction between propyne and forma ldehyde reveals that negative electrostatic potential is generated around the carbonyl oxygen and acetylenic group. The generated electrostatic potential controls the orientation of the oxygenated substituent present on the forming cyclohexane ring in ene cyclisation. Data from the study of mono substituted transition structures have been used to rationalize the stereoselectivity of an ene cyclisation with poly oxygenated substituents. |
