To drive the mechanistic studies of iron recognition in gramineous plant forward, it has been essential to establish efficient methods for mugineic acid derivatives to be utilized as molecular probes. We have recently found that the 2'-hydroxy group can serve as a potential clue for the labeling of mugineic acid analogues. On the basis of this discovery, we have established efficient method for the synthesis of various labeled mugineic acid. All of iron complexes of the synthetic labeled mugineic acid exhibit iron transport abilities through iron transporter. We thus succeed to establish the efficient method for introducing various labels to mugineic acid.
