1-Aminopentane is an organic compound with the formula CH 3 (CH 2) 4 NH 2. It is used as a solvent , as a raw material in the manufacture of a variety of other compounds, including dyes, emulsifiers , and pharmaceutical products, [ 1 ] and as a flavoring agent .
[1] [2] Azlactone chemistry: step 2 is a Perkin variation. Hippuric acid, the benzamide derivative of glycine, cyclizes in the presence of acetic anhydride, condensing to give 2-phenyl-oxazolone. [3] This intermediate also has two acidic protons and reacts with benzaldehyde, acetic anhydride and sodium acetate to a so-called azlactone.
The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution. [ 1 ] [ 2 ] The actual physiological potential depends on the ratio of the reduced ( Red ) and oxidized ( Ox ) forms according to the Nernst equation and the thermal voltage .
A classic named reaction is the Mignonac reaction (1921) [13] involving reaction of a ketone with ammonia over a nickel catalyst. An example of this reaction is the synthesis of 1-phenylethylamine from acetophenone: [14] Reductive amination acetophenone ammonia. Additionally, many systems catalyze reductive aminations with hydrogenation ...
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
The silyl-Hilbert-Johnson (SHJ) reaction (or Vorbrüggen reaction), the mildest general method for the formation of nucleosides, is the combination of a silylated heterocycle and protected sugar acetate (such as 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose) in the presence of a Lewis acid. [6]
Thus, the two substrates of this enzyme are UDP-glucose and (indol-3-yl)acetate, whereas its two products are UDP and 1-O-(indol-3-yl)acetyl-beta-D-glucose. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:(indol-3-yl)acetate beta-D ...
