چکیده
The asymmetric unit of the title compound, C23H16OS, contains two independent mol-ecules with opposite orientations of the meth-oxy groups bonded to the benzene rings. The napthobenzothiophene group in the two molecules is separated by an average distance of 3.912 Å. In both mol-ecules, the napthobenzothio-phene unit is almost planar, with r.m.s deviations of 0.0522 and 0.0143 Å. The meth-oxy-phenyl ring makes dihedral angles of 67.0 (6)° and 70.4 (6)° with respect to the napthobenzothio-phene ring system in the two mol-ecules. The crystal packing features C-H⋯S, π-π [centroid-centroid distances = 3.666 (10) and 3.658 (10) Å] and C-H⋯π inter-actions, forming a sheet running along the b-axis direction.

In the 1- (4-fluorophenyl) -2,3-dihydro-1 H-naphto- [1 and 2-e] [1 and 3] oxazine-3-n, there are 4 rings, respectively, rings from the side attached to the halogen They are named C, B, A, and D. Calculations and studies show that the amount of aromatics in the halogen-ring A in all cases has the highest number. In the B loop, the predicted aromatism level is zero, and in the ring C and D, relat...
متن کاملMicellar electrokinetic chromatography (MEKC) separation of furanonaphthoquinones from Tabebuia impetiginosa.
The separation of nine furanonaphthoquinones by micellar electrokinetic chromatography (MEKC) is described. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.09 M borate buffer (pH 9) containing 10% methanol, with an applied voltage of 20 kV. Application of this technique in the determination of the main furanonaphthoquinones, 5-hydroxy-2-(1-hydroxyethy...
