    • The most instructive piece of data was the presence of a NOESY cross-peak between the C-2 and C-5 protons in the minor isomer that was not observed in the major isomer (see Supplementary data). Examination of molecular models suggested reasonable conformations could be generated for the minor isomer, but not for the major isomer, which would place these two protons in sufficient proximity to observe an NOE
