Reaction between amine and aldehyde
WebKnoevenagel reaction is a condensation between an aldehyde or a ketone with an active hydrogen compound in the presence of a basic catalyst to yield α, β -unsaturated compounds. Usually the catalyst is a weakly basic amine, and the active hydrogen compound bears electron-withdrawing groups such as CO 2 R, COR, CHO, CN, or NO 2. WebApr 13, 2024 · The inspiration is drawn from the venerable Ugi reaction, which enables one-pot synthesis of α-amino carboxyl derivatives from amines, aldehydes, carboxylic acids …
