The Stobbe condensation entails the reaction of an aldehyde or ketone with an ester of succinic acid to generate alkylidene succinic acid or related derivatives. [1] The reaction consumes one equivalent of metal alkoxide. Commonly, diethylsuccinate is a component of the reaction. The usual product is salt of the half-ester.
Being a diester, diethyl succinate is a particularly versatile building block. It participates in acyloin condensation to give 2-hydroxycyclobutanone. [1] Via condensation with oxalate esters, it serves as a precursor to ketoglutaric acid. [2]
Dibasic ester or DBE is an ester of a dicarboxylic acid.Depending on the application, the alcohol may be methanol or higher molecular weight monoalcohols. Mixtures of different methyl dibasic esters are commercially produced from short-chain acids such as adipic acid, glutaric acid, and succinic acid. [1]
Succimer is an isomer of 2,3-dimercaptosuccinic acid. 2,3-dimercaptosuccinic acid is the organosulfur compound with the formula HO 2 CCH(SH)CH(SH)CO 2 H. This colorless solid contains two carboxylic acid and two thiol groups, the latter being responsible for its mildly unpleasant odour.
A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.
In chemistry, 2,2,3,3-tetramethylsuccinic acid or 2,2,3,3-tetramethylbutane-1,4-dioic acid is a dicarboxylic acid with the formula C 8 H 14 O 4, or HOOC-C(CH 3) 2-C(CH 3) 2-COOH. [1] [2] It can be seen as derivative of succinic acid (butane-1,4-dioic acid) with two methyl groups replacing two hydrogen atoms on each of the central carbon atoms ...
For example, diethyl oxalate condenses with cyclohexanone to give the diketo-ester, a precursor to pimelic acid. [8] With diamines, the diesters of oxalic acid condense to give cyclic diamides. Quinoxalinedione is produced by condensation of dimethyloxalate and o-phenylenediamine: C 2 O 2 (OMe) 2 + C 6 H 4 (NH 2) 2 → C 6 H 4 (NHCO) 2 + 2 MeOH
It is the acyl chloride derivative of succinic acid and a simple diacid chloride. It is a colorless liquid. It is a colorless liquid. It used as a reagent in organic synthesis .
