Abstract: Structural and theoretical studies of four novel 5,6-dehydronorcantharidine (DNCA)/norcantharidine (NCA) derivatives, namely (3aR,4S,7R,7aS)-2-phenyl-3a,4,7,7a-tetrahydro-4,7-epoxy-1H-isoindole-1,3(2H)-dione, C14H11NO3 (DNCA-A), (3aR,4S,7R,7aS)-2-(4-nitrophenyl)-3a,4,7,7a-tetrahydro-4,7-epoxy-1H-isoindole-1,3(2H)-dione, C14H10N2O5 (DNCA-NA), (3aR,4S,7R,7aS)-2-(4-nitrophenyl)-3a,4,5,6,7,7a-hexahydro-1H-4,7-epoxyisoindole-1,3(2H)-dione, C14H12N2O5 (NCA-NA), and (3aR,4S,7R,7aS)-2-(2-hydroxyethyl)-3a,4,5,6,7,7a-hexahydro-1H-4,7-epoxyisoindole-1,3(2H)-dione, C10H13NO4 (NCA-AE), are reported. The supramolecular interactions and single-crystal structural characteristics of…

DOI: 10.1107/s2056989021006952
Abstract: The asymmetric unit contains one-half of the formula unit of the title compound. The crystal structure is stabilized by intermolecular C—H⋯O, C—H⋯Cl and C—Cl⋯π interactions, and short intermolecular Cl⋯O and Cl⋯Cl contacts, forming a three-dimensional…
