The Favorskii rearrangement is principally a rearrangement of cyclopropanones and α-halo ketones that leads to carboxylic acid derivatives. In the case of cyclic α-halo ketones, the Favorskii rearrangement constitutes a ring contraction.
Acetylcholine is a choline molecule that has been acetylated at the oxygen atom. Because of the charged ammonium group, acetylcholine does not penetrate lipid membranes. . Because of this, when the molecule is introduced externally, it remains in the extracellular space and at present it is considered that the molecule does not pass through the blood–brain
Acetyl-CoA is an intermediate in the biological synthesis and in the breakdown of many organic molecules. Acetyl-CoA is also created during the second stage of cellular respiration (pyruvate decarboxylation) by the action of pyruvate dehydrogenase on pyruvic acid. [8] Proteins are often modified via acetylation, for various purposes.
In this case, the cyanide anion is the synthetic equivalent for the − COOH synthon, while benzyl bromide is the synthetic equivalent for the benzyl synthon. The synthesis of phenylacetic acid determined by retrosynthetic analysis is thus: PhCH 2 Br + NaCN → PhCH 2 CN + NaBr PhCH 2 CN + 2 H 2 O → PhCH 2 COOH + NH 3
In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen.
The Kulinkovich reaction describes the organic synthesis of substituted cyclopropanols through reaction of esters with dialkyldialkoxytitanium reagents, which are generated in situ from Grignard reagents containing a hydrogen in beta-position and titanium(IV) alkoxides such as titanium isopropoxide. [1]
The reaction is named after Cläre Hunsdiecker and her husband Heinz Hunsdiecker, whose work in the 1930s [5] [6] developed it into a general method. [1]The reaction was first demonstrated by Alexander Borodin in 1861 in his reports of the preparation of methyl bromide (CH 3 Br) from silver acetate (CH 3 CO 2 Ag).
