Abstract
Density functional theory has been used to study four pericyclic, or pseudopericyclic, reactions that may be involved in the reductive transformation of o-nitrostyrenes to indoles. These are two electrocyclizations and two 1,5-hydride shifts. The reactions of substituted examples show computed relative barrier heights in agreement with experimental observations.
Key words
pericyclic reactions - indoles - electrocyclic reactions - rearrangements - substituent effects
