1,6,6-Trimethyl-1H-chromeno[6,7-d]thia-zol-2(6H)-one.

ABSTRACT: The title compound, C(13)H(13)NO(2)S, was prepared by a thermocyclization reaction from 3-methyl-6-(2-methyl-but-3-yn-2-yl-oxy)benzo[d]thia-zol-2(3H)-one. In the crystal structure, the methyl-thia-zole unit is planar, while the pyran ring assumes a screw-boat conformation. Intra-molecular C-H?O hydrogen bonding helps to stabilize the molecular structure.

4-(2,4,6-Trimethyl-benz-yl)-1,3-thia-zol-2-amine.

Project description:The methyl-ene C atom in the title compound, C(13)H(16)N(2)S, is connected to a five-membered thia-zole ring and a mesityl substituent. The rings are aligned at 75.4 (1)°. The amino substitutent inter-acts with the ring N atom of an adjacent mol-ecule by an inter-molecular N-H⋯N hydrogen bond, generating a helical chain running along the b axis.

N-(1,3-Thia-zol-2-yl)-2-(2,4,6-trimethyl-phen-yl)acetamide.

Project description:In the title compound, C(14)H(16)N(2)OS, the thia-zole ring is essentially planar (r.m.s. deviation = 0.005 Å) and it forms a dihedral angle of 75.21 (8)° with the benzene ring. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯N hydrogen bonds to generate R(2) (2)(8) loops.

2-(6-Bromo-benzo[d]thia-zol-2-yl)-5,5-di-methyl-thia-zol-4(5H)-one.

Project description:The title compound, C12H9BrN2OS2, was obtained by reacting 6-bromo-benzo[d]thia-zole-2-carbo-nitrile in iso-propanol with ethyl 2-mercapto-2-methyl-propano-ate at reflux temperature for several hours. The resulting di-methyl-oxyluciferin derivative shows partial double-bond character of the carbon-carbon bond between the two heterocyclic moieties [C-C = 1.461 (3) Å]. This double bond restricts rotation around this C-C axis, therefore leading to an almost planar mol-ecular structure [N-C-C-S torsion angle = 9.7 (3)°]. The five-membered thiazoline ring is not completely planar as a result of the bulky S atom [C-S-C-C torsion angle = 5.17 (12)°].

Crystal structure of 2-[(3aS,6R)-3,3,6-trimethyl-3,3a,4,5,6,7-hexa-hydro-2H-indazol-2-yl]thia-zol-4(5H)-one.

Project description:The title compound, C13H19N3OS, is a new thia-zolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thio-semicarbazone pulegone. It crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The compound is composed of a hexhydro-indazole ring system (viz. a five-membered di-hydro-pyrazole ring fused to a cyclo-hexyl ring) with a thia-zole-4-one ring system attached to one of the pyrazole N atoms (at position 2). The overall geometry of the two mol-ecules differs slightly, with the mean planes of the pyrazole and thia-zole rings being inclined to one another by 10.4 (1)° in mol-ecule A and 0.9 (1)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked via C-H⋯O hydrogen bonds, forming slabs parallel to the ab plane. There are C-H⋯π inter-actions present within the layers, and between the layers, so forming a three-dimensional structure.

The crystal structures of two isomers of 5-(phenyl-iso-thia-zol-yl)-1,3,4-oxa-thia-zol-2-one.

Project description:The syntheses and crystal structures of two isomers of phenyl iso-thia-zolyl oxa-thia-zolone, C11H6N2O2S2, are described [systematic names: 5-(3-phenyl-iso-thia-zol-5-yl)-1,3,4-oxa-thia-zol-2-one, (I), and 5-(3-phenyl-iso-thia-zol-4-yl)-1,3,4-oxa-thia-zol-2-one, (II)]. There are two almost planar (r.m.s. deviations = 0.032 and 0.063 Å) mol-ecules of isomer (I) in the asymmetric unit, which form centrosymmetric tetra-mers linked by strong S⋯N [3.072 (2) Å] and S⋯O contacts [3.089 (1) Å]. The tetra-mers are π-stacked parallel to the a-axis direction. The single mol-ecule in the asymmetric unit of isomer (II) is twisted into a non-planar conformation by steric repulsion [dihedral angles between the central iso-thia-zolyl ring and the pendant oxa-thia-zolone and phenyl rings are 13.27 (6) and 61.18 (7)°, respectively], which disrupts the π-conjugation between the heteroaromatic iso-thia-zoloyl ring and the non-aromatic oxa-thia-zolone heterocycle. In the crystal of isomer (II), the strong S⋯O [3.020 (1) Å] and S⋯C contacts [3.299 (2) Å] and the non-planar structure of the mol-ecule lead to a form of π-stacking not observed in isomer (I) or other oxa-thia-zolone derivatives.
