General description

Diethyl acetylenedicarboxylate is a protein cross-linker.

Diethyl acetylenedicarboxylate is used as a Michael acceptor for O-vinyl oximes synthesis, and is used in the nucleophilic addition reaction.

Application

Diethyl acetylenedicarboxylate was used in the synthesis of:
  • 3,4,5-trisubstituted 2(5H)-furanone derivatives
  • highly functionalized thiazolidinone derivatives
  • novel cyclic peroxide glucosides
  • 4,11-dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction

A soluble bisanthene derivative, 4,11-dimesitylbisanthene, has been synthesized in three steps from bianthrone. In hot toluene, this bisanthene undergoes a clean Diels-Alder reaction with diethyl acetylenedicarboxylate to give a rearomatized 1:1 cycloadduct and, more slowly, a rearomatized 2:1 cycloadduct. In

A series of 3,4,5-trisubstituted 2(5H)-furanone derivatives was synthesized through one-pot reaction of amines, aldehydes and diethyl acetylenedicarboxylate. Silica sulfuric acid efficiently catalyzes the 3-component reaction to afford the corresponding 2(5H)-furanones in high yields. The synthesized compounds were tested against HEPG2
