A [2]rotaxane was produced through the assembly of a picolinaldehyde, an amine, and a bipyridine macrocycle around a Cu(I) template by imine bond formation in close-to-quantitative yield. An analogous [3]rotaxane is obtained in excellent yield by replacing the amine with a diamine, thus showing the suitability of the system for the construction of higher order interlocked structures. The rotaxa...

In the title Schiff base, C14H13NO4, which adopts the phenol-imine tautomeric form, the dihedral angle between the planes of the benzene and heterocyclic (r.m.s. deviation = 0.037 Å) rings is 53.31 (11)°. An intra-molecular O-H⋯N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds to generate C(11) chains propagating in the [010] direction. A weak C-...

In the mol-ecule of the title compound, C(16)H(17)NO(3), the aromatic rings are oriented at a dihedral angle of 29.25 (8)°. An intra-molecular O-H⋯N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034 (13) Å] six-membered ring, which is oriented at dihedral angles of 0.91 (1) and 28.91 (12)° with respect to the aromatic rings. The title mol-ecule is a phenol-imine...

Although an imine intermediate has long been postulated as participating in the reaction catalyzed by glutamate dehydrogenase (EC 1.4.1.4), direct evidence for a kinetically competent intermediate of this kind has not heretofore been found. We have sought such evidence by studying the exchange of the carbonyl oxygen atom of alpha-ketoglutarate in a variety of binary, ternary, and quaternary enz...

When fed the right food, hermit crab depicted in cover image grows bigger and finally needs a larger shell. This work reports reactivity of 1-phospha-2-azanorbornene, product hetero Diels-Alder reaction between 2H-phosphole an activated imine. Thus, reductive cleavage phosphorus−nitrogen bond with LiAlH4 leads to unprecedented ring expansion formation 1-phosphabicyclo[3.2.1]octa-2,5-diene. The ...

The traditional Staudinger/aza-Wittig reaction represents one of the most powerful tools for imine formation. However, this multistep procedure, sacrificial phosphine has to be used, resulting in difficulties purification process and waste disposal at same time. Here, we report a redox-neutral azide–alcohol imination methodology enabled by base-metal nickel PN3 pincer catalyst. one-step, waste-...

In this communication, we present the crystal structure of a secondary amine: 4-chloro-N-(1-(pyridin-2-yl)ethyl)aniline (Lb) obtained from stepwise reduction an imine, (E)-N-(4-chlorophenyl)-1-(pyridin-2-yl)ethan-1-imine (La) with sodium borohydride. The was characterized by FT-IR, 1H and 13C NMR, Mass Spectroscopy X-ray diffraction.

with the aim of obtaining information about drug-drug interaction (ddi) between acetaminophen and some of antidepressant drugs (fluoxetine, sertraline and nortriptyline), in the present work we studied the electrochemical oxidation of acetaminophen (paracetamol) in the presence of these drugs by means of cyclic voltammetry and controlled-potential coulometry. the reaction between n-acetyl-p-ben...
