ABSTRACT
The first total syntheses of beauvericin A and allo-beauvericin A were achieved. N-Methyl-l-phenylalanine, (2R)-hydroxylvaleric acid, and (2R,3S)- or (2R,3R)-2-hydroxy-2-methylpentanoic acid were linked and cyclized to form the target natural products. The structure of synthetic beauvericin A was confirmed by X-ray crystallographic analysis. NMR data of the synthetic beauvericins were identical with those of the reported natural products. These results secure the structures of natural products, as originally proposed in the isolation studies.
