The stereostructure of codonopsinine has been revised from 1 to 7 based on chemical correlation studies, NOE experiments, and-X-ra; crystallographic analysis. This establishes the absolute configuration of natural (-)-codonopsinine as 2R,3R,4R,5R.
The structure of hippospongic acid A was reinvestigated and new evidence supporting the revised structure previously proposed was obtained. The structure, including absolute configuration, was established by the enantioselective synthesis.
