amino acids and peptides 3 and 5-8 were synthesized and their thermal reactivity towards Bergmancyclization studied and compared with the earlier reported amino acid 4, which demonstrated, for the first time, the effect of H-bonding and electrostatic interactions in lowering the activation energy of Bergmancyclization.
