General description

Diethyl malonate is an active methylene compound that can be used as a flavoring agent in the food industry.

Application


  • Synthesis and biological activities of novel structural analogues of 2-arachidonoylglycerol, an endogenous cannabinoid receptor ligand.: This study by Suhara et al. focuses on the synthesis of novel structural analogues of 2-arachidonoylglycerol, an endogenous ligand for cannabinoid receptors. The research highlights the utilization of diethyl malonate in the synthesis process, emphasizing its importance in creating biologically active compounds with potential therapeutic applications in modulating cannabinoid receptor activity (Suhara et al., 2001).

Novel 5'-norcarbocyclic adenosine phosphonic acid analogues with 6'-electropositive moiety such as spirocyclopropane were designed and synthesized from the commercially available diethylmalonate 5. Regioselective Mitsunobu reaction proceeded in the presence of an allylic functional group at a low reaction temperature in
