Abstract
PURPOSE: The hydroxyl in α-hydroxy-γ-butyrolactone is tetrahydropyranylated, and its imino and carboxyl groups are protected, then the skelton of mugineic acid is built up, then the protecting groups are removed in order to give the titled compounds.
CONSTITUTION: α-Hydroxy-γ-butyrolactone, after its hydroxyl is tetrahydro- pyranylated, is ring-opened and at the same time the carboxyl is benzylated to give the compound of formulaI. The product is oxidized and coupled with α- amino-γ-butyrolactone to form the compound of formula II. The imino group in the compound is protected and the ring is opened and simultaneously esterified with benzyl to give the compound of formula III. The compound is oxidized and coupled with an azetidine-2-carboxylic ester to prepare the compound of formula IV. Then, the benzyl group is eliminated reductively with hydrogen in the presence of Pd-C catalyst and a trace amount of hydrogen chloride, further the other protecting groups are removed with trifluoroacetic acid to produce 2-deoxymugineic acid of formula V.
