Chemical investigation of alkaloids from Garrya ovata var. lindheimeri Torr. has led to the isolation and characterization of two new C20-diterpenoid alkaloids, ovatine (1) and lindheimerine (2), as well as the alkaloid garryfoline (3). Ovatine and garryfoline each exists as a mixture of C(20)-epimers; these alkaloids were chemically interconverted in high yield.
