Plant growth regulators in Eucalyptus grandis. VI. Reaction of the G-regulators with nucleophiles

Abstract

The formation of Michael adducts from the G-regulators and analogues with amines is described. Such adducts are, in general, unstable zwitterionic compounds and are decomposed by the action of acid into the parent G-regulator and the related 2-aminomethylene 1,3-diketone. Analogies are drawn with the natural storage and release in vivo.
