(+)-Coclaurine, (+)-stepharine, (—)-grisabine, and a new bisbenzylisoquinoline alkaloid, (+)-2-norlimacusine (1), have been isolated from Sciadotenia eichleriana. The structure of 1 has been determined by spectral data and N-methylation into (+)-limacusine. © 1985, American Chemical Society. All rights reserved.
