Total synthesis of the compound (1) having the proposed structure for the horsetail alkaloid palustrine was achieved stereoselectively in a racemic form. The synthesized compound (1), whose structure was proved by X-ray analysis, was not identical with palustrine, and therefore, the structure of palustrine should be re-investigated.
