| Abstract: | The absolute configuration of the pyrrolizidine alkaloid acetylgynuramine was determined by X-ray diffraction to be (?)-(1aR,6bR,10R,11S)-9,14-dioxo-10-hydroxy-13-cis-ethylidene-11-methoxyacetyl-10-methyl-1a,2,3,6b-tetrahydro-5H-pyrrolizino-(1a,6b,6a,b,c)-1,8-dioxa-cyclododecane. |
| Keywords: | Compositae acetylgynuramine pyrrolizidine alkaloid absolute configuration X-ray diffraction. |
