(5R,8R)-2-(3,8-Dimethyl-2-oxo-1,2,4,5,6,7,8,8a-octahydroazulen-5-yl)acrylic acid (rupestonic acid)
The title compound, C(15)H(20)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the seven-membered ring adopts a chair conformation. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains extending in the [201] direction. The absolute configuration was assigned on the basis of the starting materials.

The structure of the title compound, C(6)H(4)O(3)S, displays inter-molecular hydrogen-bonding dimers. The structure exhibits a thienyl-ring flip disorder of the main mol-ecule [occupancy ratio = 91.3 (2):8.7 (2)].

Single crystals of the title compound, C(10)H(11)NO(4), an inter-mediate in the industrial synthesis of yellow azo pigments, were obtained from the industrial production. The mol-ecules crystallize as centrosymmetic dimers connected by two symmetry-related N-H⋯O=C hydrogen bonds. Each mol-ecule also contains an intra-molecular N-H⋯O=C hydrogen bond. The dimers form stacks along the a-axis direc...

In the title herbicideh/phytocide, known as imaza-pic, C(14)H(17)N(3)O(3), the pyridine and imidazole rings are almost coplanar [dihedral angle = 3.08 (5)°]. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, an N-H⋯O hydrogen bond links mol-ecules into a chain parallel to [010].

In the title compound, C(14)H(18)N(2)O(6)·C(2)H(6)OS, the -C(O)NHCH(2)CO(2)H and -O(CH(2))(2)CH(CH(3))(2) substitutents of the aromatic ring are positioned such that the -NH- group is hydrogen-bond donor to the ether O atom of the other substituent. The dimethyl sulfoxide solvent mol-ecule is linked to the carb-oxy-lic acid group by an O-H⋯O hydrogen bond.
