J. Nat. Prod., 67, 1711 (2004)

From my experience I would estimate that approximately 5% of all C=C-C=O fragments, like cinnamic acids, coumarins, etc. have been misassigned in the chemical literature.

An example from the newer literature can be found in J.Nat.Prod.,67,1711(2004) when paying attention to the assignment of compound #13.

Again an investment of approximately 10 milliseconds of CPU-time shows this assignment error. Within the CSEARCH-environment, the NN-calculation can be activated during data-display, which analyzes every entry on-the-fly.
