A variety of different aminobenzoates have been identified as characteristic building blocks for the construction of structurally unique and biologically important natural products.[1] In this structural class, 2-aminobenzoate (anthranilate) and 4-aminobenzoate (p- aminobenzoate, PABA) are well-known compounds that are derived from chorismate, which is a key intermediate in the biosynthesis of the aromatic amino acids L-phenylalanine and ...
