摘要:
Stereoselective total synthesis of mugineic acid (1), a unique phytosiderophore from roots of barley, has been achieved from madily available (2S,3S)- and (2R,3R)-2,3-epoxycinnamyl alcohols (5) and (6). The key step is the oxidation of the phenyl group to the carboxylic acid by use of the ruthenium trichloride-sodium metaperiodate system.
