  • Determination of the absolute configuration of the novel anti-trypanosomal iridoid molucidin isolated fromMorinda lucida by X-ray analysis

  • The strong anti-trypanosomal active compound, molucidin, contains a spirolactone tetracyclic iridoid skeleton and is isolated fromMorinda lucidaas an enantiomer of oruwacin, which is isolated from the same plant. To confirm the absolute configuration of molucidin, we prepared single crystals of molucidin for X-ray analysis. The absolute configuration of the afforded single crystal was determined by X-ray crystallography using a Cu radiation source. X-ray diffraction data were collected at 93 K in the 2hrange 7.468–134.99 and analyzed using the SHELXL-2014 program. The corresponding chiral quaternary carbon atoms in molucidin were unambiguously determined as 1R,5S,8S,9S, and 10S...
