Abstract

A new monoterpene indole alkaloid, naucleamide F (1), has been isolated from the bark and wood of Nauclea latifolia, and the structure and stereochemistry were elucidated on the basis of the spectral data. Naucleamide F (1) is a new monoterpene indole alkaloid consisting of a tetrahydro-β-carboline ring fused to a pyridone ring, and a 1,3,5-trioxepane ring fused to a dihydropyran ring and a glucose unit.
