diseases. In the present study, a series of 47 carbamazepine derivatives including 32 novel compounds were designed, synthesized, and evaluated as P2X4 receptor antagonists. Their potency to inhibit ATP-induced calcium influx in 1321N1 astrocytoma cells stably transfected with the human P2X4 receptor was determined. Additionally, species selectivity (human, rat, mouse) and receptor subtype selectivity (P2X4

Expecting the unexpected: The title reaction leads to satisfactory yields of dihydrodibenzoazepines 1 a from norbornene. The dibenzoazepines 2 can also be accessed from compounds of type 1 b when norbornadiene is used as a reactant. Theoretical studies show that the reaction represents a chelation‐driven deviation from the usual selectivity observed in the presence of ortho‐substituents on the aryl
