Description
Summary:The chemical study of Villasenoria orcuttii, the only species of the genus Villasenoria, afforded three acyclic diterpenes, two of them described for the first time. Two pyrrolizidine alkaloids, florosenine and floridanine, among other known compounds were also isolated. The absolute configuration of floridanine was determined by X-ray analysis using anomalous dispersion with Cu Kαradiation, and its¹ H and13 C nuclear magnetic resonance (NMR) data were corrected.
