چکیده
In the title compound, C(10)H(13)NO(2)S, the thio-phene and isoxazoline rings are almost coplanar, the dihedral angle between their least-squares planes being 2.08 (1)°. The O-H atoms of the methyl hy-droxy group and the N atom of the isoxazole ring are orientated in the same direction to allow for the formation of inter-molecular O-H⋯N hydrogen bonds that lead to a supra-molecular chain along the a axis.

The title mol-ecule, C20H20N2S2, is T-shaped and consists of a nearly flat 5,6-dimethyl-2-(5-methyl-thio-phen-2-yl)benzimidazole system approximately perpendicular to the 5-methyl-thio-phen-2-ylmethyl substituent. The 5,6-dimethyl-2-(5-meth-yl-thio-phen-2-yl)benzimidazole system is rotationally disordered about the two imidazole N atoms as approximated by a twofold rotation axis with a refined ...

The crystal structure of the title compound, C29H16F6N2S2·0.5CHCl3, consists of mol-ecules with disordered perfluoro-cyclo-pentene rings [occupancy ratio 0.685 (3):0.315 (3)] and close F⋯F contacts (in the range 2.45-2.73 Å) between mol-ecules. The short contacts are associated with the disorder. The dihedral angle between thiophene rings is 57.44 (8)°. The 5-(4-cyano-phen-yl)-3-methyl-2-thieny...

The synthesis of the (2S)-[3-(anthracen-9-yl)-4,5-dihydroisoxazol-5-yl]methyl 2-[(tert-butoxycarbonyl)amino]propanoate is obtained through the 1,3-dipolar cycloaddition of the stable anthracenenitrile oxide and the N-Boc protected (S)-alanine allyl ester as dipolarophile. The structure and the fluorescence properties are described upon the relative analytical and spectroscopic data.

The mol-ecule of the title compound, C(12)H(15)ClF(3)N(3)O(3)S, is twisted, as indicated by the C-S-C-C torsion angle of 66.00 (18)° for the atoms linking the ring systems. An intra-molecular C-H⋯F short contact occurs. In the crystal, non-classical C-H⋯O inter-actions, one of which has a short H⋯O contact of 2.28 Å, link the mol-ecules.
