The Structure and Synthesis of Cytokinin Metabolites. II. Lupinic Acid and O-β-D-Glucopyranosylzeatin From Lupinus angustifolius

Abstract

Two new metabolites of exogeneously supplied zeatin have been identified in de-rooted lupin seedlings as L-lupinic acid (2) and O-β- D-glucopyranosylzeatin (3). Their structures have been confirmed by syntheses which provide new and general methods for the preparation of these types of compounds.
