Diethyl acetylenedicarboxylate is used as a protein cross-linker. It is also used in the synthesis of 3,4,5-trisubstituted 2 5H -furanone derivatives, highly functionalized thiazolidinone derivatives, novel cyclic peroxide glucosides and 4,dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction. Reactions of salicyl N-tosylimines or salicylaldehydes with diethyl acetylenedicarboxylate for the synthesis of highly functionalized chromenes.

Stock No. Soluble in ethanol, ethyl ether, CCl4, Insoluble in water.

Protect from heat. Store away from oxidizing agents. Incompatible with strong acids and strong bases. Reaction with enamines leads to 2 1H -pyridones: Synthesis Other References Beilstein.Their biological effects are due in large part to their electrophilic properties, whereby they undergo reaction with nucleophilic sites in proteins and nucleic acids. Here, we describe a structure-activity comparison of the cytotoxic properties of diethyl maleate DEM and closely related chemical analogs.

However, related molecules lacking this chemical moiety were not cytotoxic. One of the molecules screened, diethyl acetylenedicarboxylate DADwas considerably more cytotoxic than DEM and other analogues.

Induction of cell death by DAD was significantly decreased following preincubation of cells with N-acetylcysteine, suggesting that its reactivity with thiols in cells might account for its cytotoxicity. By use of a model thiol compound, it was found that DAD can undergo addition reactions with two equivalents of thiol.

When the reactivity of DAD with proteins was explored, it was determined that DAD induces oligomerization of Gpx3p, a yeast glutathione peroxidase with highly reactive cysteine residues in its active site. Our results suggest that DAD functions as a protein-thiol cross-linker, providing a potential chemical explanation for its cytotoxic potency. Publication types Research Support, Non-U.It is a crystalline solid that is soluble in diethyl ether.

The acid was first described in by Polish chemist Ernest Bandrowski. The reaction yields potassium bromide and potassium acetylenedicarboxylate.

The salts are separated and the latter is treated with sulfuric acid. Acetylenedicarboxylic acid is used in the synthesis of dimethyl acetylenedicarboxylatean important laboratory reagent.

The acid is commonly traded as a laboratory chemical. It can also be reacted with sulfur tetrafluoride to produce hexafluorobutynea powerful dienophile for use in Diels-Alder reactions.

Acetylenedicarboxylic acid

Fatty alcohol esters of acetylenedicarboxylic acid can be used for the preparation of phase change materials PCM. The anion can be derived from acetylenedicarboxylic acid by removal of a single proton or from the acetylenedicarboxylate dianion by addition of a proton.

The name is also used for any salt of this anion. Salts of this anion are of interest in crystallography because they contain unusually short and strong hydrogen bonds. In many crystalline salts with the exception of the lithium onethe HADC units form linear chains connected by strong hydrogen bonds. Each carboxylate group is usually planar; but the two groups may lie in different planes due to rotation about the carbon—carbon bonds.

It is often called potassium hydrogen acetylenedicarboxylate or monopotassium acetylenedicarboxylate. The salt can be obtained from acetylenedicarboxylic acid and is a common laboratory starting material for the synthesis of other derivatives of that acid.

In the crystalline form, the hydrogenacetylenedicarboxylate anions are joined into linear chains by uncommonly short hydrogen bonds. The anion can be derived from acetylenedicarboxylic acid by the loss of two protons. From Wikipedia, the free encyclopedia. Redirected from Acetylenedicarboxylate.
