New oxime ethers and pesticidal and herbicidal preparations containing them are disclosed. The oxime ethers correspond to the formula ##SPC1## Wherein R.sub.1 is a hydrogen atom or a lower alkyl radical; R.sub.2 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical; or wherein R.sub.1 and R.sub.2 form part of a saturated or unsaturated carbocycle or a 5-, 6- or 7-membered heterocycle; R.sub.3 is a nitro, trifluoromethyl, formyl, lower carbalkoxy, sulfamyl or mono- or di-lower alkyl sulfamyl radical; R.sub.4.sub.- and R.sub.5.sub.- each is a hydrogen or halogen atom, an amino, mono- or di-lower alkyl amino, lower alkoxy, cycloalkoxy, lower alkylthio, nitro, lower carbalkoxy, arylthio, lower aralkylthio or lower alkyl group, or 5-, 6- or 7-membered heterocycle.
A new series of oximeethers 4a–z was designed and synthesized to test the blocking activity against β1 and β2-adrenergic receptors. Docking of these ether derivatives into the active site of the identified 3D structures of β1 and β2-adrenergic receptors showed MolDock scores comparable to those of reference compounds. Biological results revealed that the inhibition effects on the heart rate and contractility
Multinuclear magnetic resonance study of 1,3,3-trimethylbicyclo [2.2.1]heptan-2-one (fenchone) oxime, its five monochloro derivatives and a dehydrochlorination product
Fenchone oxime, 5-exo-chlorofenchone oxime, 6-exo-chlorofenchone oxime, 7-anti-chlorofenchone oxime, 8-chlorofenchone oxime, 9-chlorofenchone oxime and a dehydrochlorination product of 10-chlorofenchone oxime were synthesized from fenchone and the corresponding chlorofenchones. The 1H, 13C and 17O NMR spectra of the oximes and the dehydrochlorination product were recorded. The NMR data were compared with the corresponding parameters obtained earlier for fenchone and monochlorofenchones in order to determine the differences between the carbonyl and oxime substituents from the NMR spectroscopic point of view, and to assign the stereochemistry of the oxime group. This stereochemistry could not, however, be assigned solely by NMR spectroscopy.
