X-Ray crystallographic determination of the structure of the diterpenoid alkaloid denudatine
Abstract
Single-crystal X-ray diffraction studies of denudatine methiodide have shown that denudatine possesses an atisine-type skeleton with a C(7)–C(20) bridge: denudatine has a structure of the type which may serve as an intermediate in the biogenetic transformation of the atisine-type alkaloids to the aconitum-type alkaloids.
