In organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.
Alcohol withdrawal syndrome (AWS) is a set of symptoms that can occur following a reduction in or cessation of alcohol use after a period of excessive use. [1] Symptoms typically include anxiety , shakiness , sweating, vomiting, fast heart rate , and a mild fever. [ 1 ]
Disulfiram-alcohol reaction (DAR) is the effect of the interaction in the human body of alcohol drunk with disulfiram or some types of mushrooms. [ 1 ] [ 2 ] The DAR is key to disulfiram therapy that is widely used for alcohol-aversive treatment and management of other addictions (e.g. cocaine [ 3 ] [ 4 ] use).
[1,3] diols have a tendency to eliminate water following the monooxidation by Fétizon's reagent to form an enone. [8] Upon oxidation with Fetizon's reagent, a 1,3 diol may eliminate water to produce an enone. Under differing structural conditions, [1,2] diols can form diketones in the presence of Fétizon's reagent.
Certain clinical conditions such as type 2 diabetes mellitus and liver cirrhosis have been identified as producing higher levels of endogenous ethanol. [4] Research has also shown that Klebsiella bacteria can similarly ferment carbohydrates to alcohol in the gut, which can accelerate non-alcoholic fatty liver disease . [ 10 ]
Zieve's syndrome is an acute metabolic condition that can occur during withdrawal from prolonged heavy alcohol use. It is defined by hemolytic anemia (with spur cells and acanthocytes), hyperlipoproteinemia (excessive blood lipoprotein), jaundice (elevation of unconjugated bilirubin), and abdominal pain. [1]
Another side reaction is the Tischenko reaction of aldehyde products with no α-hydrogen, but this can be prevented by use of anhydrous solvents. [4] Another general side reaction is the migration of the double bond during the oxidation of allylic alcohol substrates. [14] Oppenauer oxidation of a steroid derivative. [15]
Under ideal conditions the reaction produces 50% of both the alcohol and the carboxylic acid (it takes two aldehydes to produce one acid and one alcohol). [5] This can be economically viable if the products can be separated and both have a value; the commercial conversion of furfural into furfuryl alcohol and 2-furoic acid is an example of this ...
