โœฆ Synopsis

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 absolute configuration of dysidenin and isodysidenin are revised. Dysidenin and isodysidenin are two highly modified peptides isolated from the sponge herbacea. Dysidea The structure of dysidenin, without stereochemistry was established by the Roche group.' The x-ray structure of isodysidenin wi
