Abstract
- Chemical investigations of Prionosciadium thapsoides roots led to the isolation of the new dihydrofurochromones (S)-(+)-4'-O-angeloyl-5-O-methylvisamminol (1) and (S)-(+)-4'-O-senecioyl-5-O-methylvisamminol (2), together with the known coumarins jatamansin, buchtormin, isopteryxin, isosamidin, psoralen, and bergapten. The structures of 1 and 2 were determined by 1D and 2D NMR experiments, and their absolute configuration was established by chemical correlation with (+)-5-O-methylvisamminol (3), whose structure was secured by single-crystal X-ray diffraction analysis and its absolute configuration was established as S by vibrational circular dichroism spectroscopy in comparison to DFT B3LYP/DGDZVP calculations.
