Alkaloids from the Traditional Chinese Medicine ChanSu: synthesis-enabled structural reassignment of bufopyramide to bufoserotonin C.

A synthesis of putative bufopyramide has shown the structure assigned to the natural product to be incorrect. The spectroscopic data for the natural product bufopyramide matches that obtained from a synthetic sample of bufoserotonin C, confirming that the two natural products are not distinct, but instead the same compound.
