| Abstract: | Transition structures (TSs) for the Lewis acid catalyzed ene cyclization reaction have been optimized quantum mechanically and the selectivity for the (3,5) ene cyclized product have been compared with that of (3,4) product. Analysis of the result shows that the geometric deformation of the TS produced due to the presence of Lewis acid in the environment plays a significant role in determining the selectivity of (3,5) ene product. This geometric deformation originates from the enlarged dihedral angle around the forming carbon-carbon bond in the Lewis acid catalyzed TS. |
