Description: Crystal structures of two isomeric norcantharidin derivatives (3R,3aR,4S,7R,7aS)-3-(allyloxy)hexahydro-4,7-epoxyisobenzofuran-1(3H)-one (7b), and (3S,3aR,4S,7R,7aS)-3-((E)-but-2-en-1-yloxy)hexahydro-4,7-epoxyisobenzofuran-1(3H)-one (8a) have been determined. In both instances the equivalent enantiomer was also obtained. The crystal structures of these compounds clarify the stereochemistry inferred only by NMR analysis before.
