A novel type of denitrifying bacterium (strain HxN1) with the capacity to oxidize n-alkanes anaerobically with nitrate as the electron acceptor to CO(2) formed (1-methylpentyl)succinate (MPS) during growth on n-hexane as the only organic substrate under strict exclusion of air. Identification of MPS by gas chromatography-mass spectrometry was based on comparison with a synthetic standard. MPS w...

In the title compound, C(13)H(17)NO, the cyclo-hexane ring adopts a chair conformation and the amide C(=O)-N moiety is almost coplanar with the phenyl ring [C-N-C-O = 4.1 (2)°]. In the crystal, mol-ecules are linked to form a C(4) infinite [001] chain via N-H⋯O hydrogen bonds, unlike the cyclic motif seen in related structures.

The title compound, C(11)H(16)O(4), crystallizes with three molecules in the asymmetric unit. The cyclo-hexane ring adopts a chair conformation. Inter-molecular O-H⋯O hydrogen bonds are observed and these help to establish the crystal packing.

In the title compound, C(13)H(16)N(2)O, the cyclo-hexane ring adopts a chair conformation. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains propagating in [001].

The crystal structure of the title compound, C(16)H(20)BrNO(3), contains three chiral centers in the configuration 1R,2S,6R. The cyclo-hexane ring is in a chair conformation. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming chains along the a-axis direction.

The pea aphid, Acyrthosiphon pisum Harris, (Homoptera: Aphididae) releases the volatile sesquiterpene (E)-beta-farnesene (EBF) when attacked by a predator, triggering escape responses in the aphid colony. Recently, it was shown that this alarm pheromone also mediates the production of the winged dispersal morph under laboratory conditions. The present work tested the wing-inducing effect of EBF...

The asymmetric unit of the title compound, C26H30N2O3 {systematic name (S)-(+)-2-[cis-4-(benz-yloxy)cyclo-hexa-ne-carb-on-yl]-1,2,3,6,7,11b-hexa-hydro-4H-pyrazino-[2,1-a]isoquin-olin-4-one}, consists of two independent mol-ecules in which the O= Camide group is syn to the N-C(C=Olactam) moiety, making dihedral angles of 2.0 (8) and 3.7 (8)°. The conformation of the 1,4-disubstituted cyclo-hexan...

In the title compound, C(19)H(33)NO, all three cyclo-hexane rings adopt chair conformations. The crystal packing features weak C-H⋯O inter-actions, forming a supra-molecular chain along the c axis.

In the title mol-ecule, C(11)H(20)N(2)S, the five-membered ring has an envelope conformation and the cyclo-hexane ring is in a chair conformation. The N-H group is not involved in any intra- or inter-molecular inter-actions.

The title compound, C(16)H(19)NO, was synthesized under solvent-free conditions by reaction of 7-oxa-bicyclo-[4.1.0]heptane and naphthalen-1-amine in the presence of Ca(CF(3)COO)(2) as catalyst. The cyclo-hexane ring adopts a chair conformation. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds and C-H⋯π inter-actions into chains parallel to the c axis.
