چکیده
In the mol-ecule of the title compound, C(19)H(17)NO(8), the benzodioxole unit is oriented at a dihedral angle of 61.45 (6)° with respect to the meth-oxy-substituted phenyl ring. The nitro group is not co-planar to the benzene ring to which it is attached, making a dihedral angle of 31.86 (17)°. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into chains through R(2) (2)(8) ring motifs. The π⋯π contacts between the benzodioxole rings, [centroid-centroid distances = 3.7610 (9), 3.6613 (9) and 3.7975 (9) Å] may further stabilize the structure.

The title chalcone (E)-1-(2-aminophenyl)-3-(benzo[d][1,3]dioxol-5-yl)prop-2-en-1-one was obtained in 76% yield from a NaOH catalyzed Claisen–Schmidt condensation reaction between o-aminoacetophenone and piperonal. This product will be used as a key precursor for the development of an alternative route for the total synthesis of the alkaloid Graveoline. Single crystals of the title compound suit...

3,4-Dihydro-2H,6H-pyrimido[1,2-c][1,3]benzothiazin-6-imine (PD 404182) is an antiretroviral agent with submicromolar inhibitory activity against human immunodeficiency virus-1 (HIV-1) and HIV-2 infection. In the current study, the structure-activity relationships of accessory groups at the 3- and 9-positions of pyrimido[1,2-c][1,3]benzothiazin-6-imine were investigated for the development of mo...
متن کاملStructural and spectral investigations of the recently synthesized chalcone (E)-3-mesityl-1-(naphthalen-2-yl) prop-2-en-1-one, a potential chemotherapeutic agent
BACKGROUND Chalcones (1,3-diaryl-2-propen-1-ones, represent an important subgroup of the polyphenolic family, which have shown a wide spectrum of medical and industrial application. Due to their redundancy in plants and ease of preparation, this category of molecules has inspired considerable attention for potential therapeutic uses. They are also effective in vivo as anti-tumor promoting, cell...
