Abstract

Semiempirical calculations support a spin-paired chair-like TS for the 3-aza-Claisen rearrangement, and yield the prediction that an anionic substituent on the nitrogen atom reduces the activation energies for the rearrangement. Attempts to demonstrate this experimentally have been unsuccessful.
