Electrocyclic Aromatic Substitution by Nitrile Ylides to give 3H-2-Benzazepines: Substituent Effects and Mechanism

Groundwater, Paul W.,Sharp, John T.

, p. 7951 - 7964 (2007/10/02)

Benzonitrile 3,3-diarylallyl nitrile ylides (16), generated by the base-induced dehydrochlorination of imidoyl chlorides, cyclised by 1,7-ring closure to give 3H-2-benzazepines e.g. (19), in contrast to analogous diazo-compounds (1) which prefer 1,5-elect
