CLEAR LIGHT YELLOW LIQUID | [Uses]
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 4,11-dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction. | [General Description]
Diethyl acetylenedicarboxylate is a protein cross-linker. | [Purification Methods]
Dissolve the ester in *C6H6, wash it with NaHCO3, H2O, dry over Na2SO4, filter, evaporate and distil it in a vacuum [IR: Walton & Hughes J Am Chem Soc 79 3985 1957, Truce & Kruse J Am Chem Soc 81 5372 1959]. [Beilstein 2 H 803.] |
