By employing triethylamine as a catalyst, [3 + 2] coupling‐elimination cascade of α,α‐dicyanoolefins with quinone monoimines was realized. The reactions afforded various novel pterocarpen analogues with generally moderate yields (up to 75%). In addition, a plausible reaction mechanism was proposed.
