Concise synthesis of arogenate. A biosynthetic precursor of phenylalanine and tyrosine
Abstract
A concise new route to arogenate [L-(8S)-β-(1-carboxy-4-hydroxy-2,5-cyclohexadien-1-yl)alanine diammonium salt]1 in which Michael addition of the anion derived from methyl 1,4-dihydrobenzoate 2 to the dehydroalanine derivative 3 is the key C–C bond-forming step is described.
