However, the NMR data of the synthetic sample did not match those reported for 2. It was then suggested that the original sample contained an additional isomer of different solubility, pseudorubriflordilactone B (3), whose structure remained unknown. From theoretical calculations, reexamination of the NMR data, and biogenetic considerations, it is proposed that 3 should be the 16S,17R isomer of 2.application/pdf6420-6423engopenAccessRubriflordilactone BX-ray CrystallographyPseudorubriflordilactone B6S,17RComputational ChemistryarticleUniversidad Nacional de RosarioAmerican Chemical SocietyGrimblat, NicolásKaufman, Teodoro SaúlSarotti, Ariel Marcelo
