Application

1-Chloro-N,N,2-trimethyl-1-propenylamine is an acid halogenation reagent developed by Ghosez, that enables the conversion of carboxylic acids into the corresponding chlorides under strictly neutral conditions. This method was successfully used in the total synthesis of caloporoside, roseophilin, (-)-enniatin B, (±)-epimeloscine and (±)-meloscine.

Acid Halogenation Reagents

The generation of an acid chloride is an obvious way to activate the carboxy group for amide bond formation. However, practical application of acid chlorides in peptide synthesis is restricted, because they are prone to side reactions and racemization.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
