Stereochemistry of cis-2-hydroxy-2-phenyl-cyclohexanecarboxylic acid (cicloxilic acid).
Arzneimittel-Forschung, 1979The configuration of cis-2-hydroxy-2-phenyl-cyclohexanecarboxilic acid (cicloxilic acid) was deduced by comparing its NMR and IR spectra with those of its diastereoisomer and of their respective analogs, the 1-hydroxy(bicyclohexyl)-2-carboxylic acids. The diastereoisomer was prepared by converting cicloxilic acid to the corresponding 2-chloro-2-phenyl ...

AbstractA description is given of the synthesis of dimeric α‐nitrosocyclohexanecarboxylic acid (III). This acid provides the first example of the hitherto unknown class of α‐nitrosocarboxylic acids. It is shown that III is not an intermediate in the nitrosodecarboxylation of cyclohexanecarboxylic acid to caprolactam.

Abstract Stereoselective synthesis of the title compounds was performed. The relative configuration of methyl t-4-(tert-butoxycarbonylamino)-c-3-hydroxy-r-1-cyclohexanecarboxylate and methyl trans-4-(tert-butoxycarbonylamino)-3-oxo-r-1-cyclohexanecarboxylate was confirmed by X-ray diffraction methods.

Conformational Analysis of IR Spectra of Alkyl and Fluoroalkyl Cyclohexanecarboxylic Acids
Journal of Structural Chemistry, 2002IR spectra were simulated for a series of alkyl and fluoroalkyl cyclohexanecarboxylic acids, whose experimental spectra have been previously recorded in the temperature range 77–500 K. The simulation was performed taking into account the conformational mobility of the molecules and a decrease in the hydrogen‐bond energy of H‐complexes during heating ...

Diversions of the Shikimate Pathway — The Biosynthesis of Cyclohexanecarboxylic Acid
1992The shikimic acid pathway1 has evolved in plants and microorganisms to provide for the synthesis of the aromatic amino acids, phenylalanine, tyrosine and tryptophan, as well as a number of other essential aromatic compounds, e.g., jo-aminobenzoic acid, the precursor of folic acid, or]D-hydroxybenzoic acid, the precursor of ubiquinone.
