Description

General description

CDI serves as a powerful coupling reagent in peptide synthesis and organic chemistry.

Application

CDI (1,1′-Carbonyldiimidazole) can be used:

• In the activation of malonic acid derivatives to prepare carbonyl imidazoles by mild decarboxylation.
• In the activation of cellulose membranes for the development of immunosensors.
• In the synthesis of substituted 1,3-oxazolo[4,5-d] pyridazinones.
• As a reagent for the conversion of various hydroxamic acids to isocyanates by Lossen rearrangement.
• In the synthesis of 1,3,4-oxadiazole derivatives , and peptide thioesters in water.
• As an acylation agent for the synthesis of carbamates.

Other Notes

Reactive reagent for the activation of acids as imidazolides: synthesis of esters, amides, ketones etc. Reagent for immobilizing enzymes and affinity ligands; Carbonyl-transfer reagent for the synthesis of various heterocycles, some recent applications
