The Reaction Between Carboxylic Acids And Amines

WebTherefore, reaction selection can influence the success or failure of a candidate molecule to meet a functional objective. The coupling of an amine with a carboxylic acid to form an amide bond is the most popular chemical reaction used for drug discovery 1. However, there are many other ways to connect these two common functional groups together. WebThe amine products were removed as the ammonium salt of a carboxylic acid anion, while the amine donors, broadly applied in a significant surplus, as well as other reactants remained in solution. For that purpose, a screening of solubility margins between the amine donor and amine product salts was performed for a variety of possible carboxylic ...
