The title compound, C(24)H(27)FN(2)O(4), is an important inter-mediate in the synthesis of fungicidal strobilurin-type compounds. In the crystal structure, the oxime bond attached to the cyclo-propane ring adopts a Z configuration, while the oxime bond attached to the benzene ring adopts an E configuration. The fluoro-methyl-phenyl group adopts a trans configuration with respect to the remainde...

We have demonstrated that oxime-based mixed carbonates are very effective reagents for both N-protection and peptide coupling.

Benzonitrile oxide (la) reach with 1,1,2,2,3,3-hexamethyl-4,5-bis(methylene)cyclopen~e (5) to give a mixture of the 1,3-dipolar cycloaddition product 8 and the oxime 9. This reaction is 26 times slower than the corresponding reaction of la with 1,2-bis(methylene)cyclopentane (15), which exclusively yields the 2-isoxazoline 19. With the assumption that the oxime 9 is generated by a stepwise proc...

The title Schiff base bis-oxime compound, C(20)H(24)N(2)O(6), lies across an inversion centre and adopts an E configuration with respect to the C=N bond. In the mol-ecule, the oxime group is roughly coplanar with the benzene ring, forming a dihedral angle of 1.77 (2)°. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring with an S(6) motif. Weak inter-molecular C-H⋯O hydrogen bondin...

In the unit cell of the title compound, C(5)H(7)N(3)O, there are two conformers (A and B) which differ in the position of the oxime group with respect to the protonated pyrazole nitro-gen (trans in the A conformer and cis in the B conformer) and in the geometric parameters. The oxime group exists in the nitroso form in both conformers. In the crystal, mol-ecules are linked by inter-molecular N-...

The title compound, [Cu(C(9)H(9)BrNO(2))(2)], is a centrosymmetric mononuclear copper(II) complex. The Cu atom is four-coordinated in a trans-CuN(2)O(2) square-planar geometry by two phenolate O and two oxime N atoms from two symmetry-related N,O-bidentate (E)-4-bromo-2-(ethoxy-imino-meth-yl)phenolate oxime-type ligands. An inter-esting feature of the crystal structure is the centrosymmetric in...

A Pd(0)-catalyzed intramolecular Heck-type reaction of oxime ether has been developed, providing convenient access to heterocyclic oximes.

Nickel(II) complex of [NiL2](ClO4)2, where L is an unsymmetrical tridentate ligand of 2-(2-aminoethyl)imino-3-butanone oximehas been synthesized by a template condensation reaction. The complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. X-ray diffraction study of the complex revea...

An efficient stereocontrolled route to ( )-cylindricine C is described. Reaction of 9-hydroxynon-1-en-5one oxime with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords a 7-oxa-1-azanorbornane cycloadduct in high yield. The formation of the bicyclic isoxazolidine arises from conjugate addition of the oxime onto the diene to give a transient nitrone that spontaneously undergoes an intramolecular dipo...
