Ketogenic diets are high-fat, low-carbohydrate interventions with energy largely derived from fatty acid oxidation, with the spillover of excess acetyl-CoA forming ketone bodies in the liver as glucose reserves are depleted. One effect of the ketogenic diet is an energetic shift from carbohydrate t...
13C NMRmass spectrometryA sesquiterpenoid, C 15H 26O, was isolated from Valeriana officinalis of which the spectral data (IR, NMR and mass spectra) were in agreement with those of faurinone. Based on 13C NMR, and 13C and 1H NMR shift and decoupling experiments a new structure for fauri...

The reaction can be analyzed by assuming that a homolytic cleavage in a [1,2] shift results in the production of a vinyl radical cation and in a [1,6] shift results in the production of a hexatriene radical cation. In case of a [1,2] shift, the HOMO of the π-framework of the...

1.1H NMR (A) and 13C NMR (B) spectra of AnBF (CDCl3). Synthesis of the polymers containing anthracene moiety Polymers containing anthracene moiety in the backbone were obtained by conventional aromatic nucleophilic polycondensation. As shown in Scheme 2, two polymers with different bisphenol ...
In alkaline medium a bathochromic shift of the absorption maximum of 80 to 160 nm can be observed, the products are pH-indicators. The conformations were established by means of 1 H-NMR-spectroscopy and correspond to two types of symmetric bis-enaminoketones. In type I both enaminoketone ...
The regioselectivity was determined by 1H NMR. b) Optimized conditions: P25 (25 mg, 0.25 mmol), 0 °C, 10 h,395 nm LED, and 0.15 mmol of substrate in 3.0 mL of CH3CN. c) The isolated yield of the major isomer is listed. To extend this method to the ...
