Catalytic hydrogenation of nitrocyclohexane could be an alternative source various useful chemicals: cyclohexanone oxime, cyclohexanone, cyclohexanol, cyclohexylamine and dicyclohexylamine.

A set of oxime carbamates having N-alkyl and N,N-dialkyl substituents were prepared via carbonyldiimidazole intermediates. It was shown by EPR spectroscopy that they underwent clean homolysis of their N-O bonds upon UV photolysis. During photolysis of acetophenone O-allylcarbamoyl oxime, the corresponding oxazolidin-2-onylmethyl radical was detected by EPR spectroscopy, providing the first evid...

This review summarizes the new carbon-carbon bond construction methods based on the radical reaction of imine derivatives. The intermolecular carbon radical addition to oxime ethers proceeded smoothly in the presence of BF3.OEt2. A high degree of stereocontrol in the reaction of oxime ethers was achieved to give amino acid derivatives with excellent diastereoselectivities. The radical reaction ...

A novel photoredox-catalyzed C(sp 3 )–C(sp ) cross-coupling between N -arylamines and cycloketone oxime esters under mild conditions has been accomplished.

In this study, a series of coumarin chromophore-based oxime-esters were designed and synthesized as visible light photoinitiators (PIs).

The synthesis and aromatase inhibitory activity of androst-4-en-, androst-5-en-, 1β,2β-epoxy- and/or androsta-4,6-dien-, 4β,5β-epoxyandrostane-, and 4-substituted androst-4-en-17-oxime derivatives are described. Inhibition activity of synthesized compounds was assessed using aromatase enzyme and [1β-3H]androstenedione as substrate. Most of the compounds displayed similar to or more aromatase in...

We report here the discovery and development of boron-assisted oxime formation as a powerful connective reaction for chemical biology. Oximes proximal to boronic acids form in neutral aqueous buffer with rate constants of more than 10 M 1 s , the largest to date for any oxime condensation. Boron's dynamic coordination chemistry confers an adaptability that seems to aid a number of elementary st...

In the crystal structure of the title compound, C(7)H(8)N(2)O, mol-ecules are connected via inter-molecular N-H⋯O and O-H⋯N hydrogen bonds to form a two-dimensional supra-molecular structure. The oxime group has an E configuration and the dihedral angle between the mean planes of the benzene ring and the amidoxime grouping is 20.2 (3)°.

Selective syntheses are now available for compounds of many classes, based on C-centered radicals, exploiting a diverse range of mechanisms. The prospect for chemistry based around N- and O-centered radicals is probably more favorable because of the importance of heterocycles as biologically active materials. Heteroradical chemistry is still comparatively underdeveloped due to the need for safe...
