4-(2,3-Di-hydro-thieno[3,4-b][1,4]dioxin-5-yl)aniline.

ABSTRACT: In the title mol-ecule, C12H11NO2S, the dioxane-type ring adopts a half-chair conformation. The thio-phene ring forms a dihedral angle of 12.53?(6)° with the benzene ring. In the crystal, N-H?O, hydrogen bonds link mol-ecules, forming chains along the c-axis direction. A weak intra-molecular C-H?O hydrogen bond is observed.

(Z)-5-(3,4,5-Tri-meth-oxy-styr-yl)-2,3-di-hydro-thieno[3,4-b][1,4]dioxine.

Project description:In the title compound, C17H18O5S, an analogue of the potent anti-cancer agent combretastatin A-4, the alkene C=C bond has a cis conformation and the C-C=C-C torsion angle is 9.0 (3)°. The dihedral angle between the benzene and thio-phene rings is 54.07 (4)°. The dioxene ring adopts a half-chair conformation, with the C atoms of the methyl-ene groups displaced by -0.325 (2) and 0.341 (3) Å from the plane of the other atoms. The C atoms of the two meta-meth-oxy groups are close to being coplanar with their attached benzene ring [displacements = -0.025 (2) and -0.196 (2) Å], whereas the C atom of the para-meth-oxy group is significantly displaced [by -1.107 (2) Å]. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into [0-11] chains, which feature two different types of R 2 (2)(6) loops.

Project description:In the title mol-ecule, C24H23N3O3S2, the benzo-thia-diazole ring system is essentially planar, with an r.m.s. deviation of 0.020?(8)?Å. The thio-phene and hy-droxy-substitiuted rings form dihedral angles of 23.43?(9) and 35.45?(9)°, respectively, with the benzo-thia-diazole ring system. An intra-molecular O-H?N hydrogen bond is observed. In the crystal, weak C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.880?(3)?Å] link mol-ecules into chains along [100]. In addition, there are short S?S contacts [3.532?(3)?Å] which link these chains, forming a two-dimensional network parallel to (010).

The dimer units are arranged to form a ribbon-like mol-ecular sheet.
