title: Eletefine, a stephaoxocane alkaloid from cissampelos glaberrima
abstract: A novel isoquinoline alkaloid bearing an oxocane ring (stephaoxocane type (Kashiwaba, N.; Morooka, S.; Kimura, M.; Ono, M.; Toda, J.; Suzuki, H.; Sano, T. J. Nat. Prod. 1996, 59, 803)), has been isolated from the roots of Cissampelos glaberrima. This compound was given the trivial name eletefine (1) and its structure assigned on the basis of spectroscopic data and conversion to the corresponding ketone (2).
