Reaction Steps

According to the study by the present inventors, it has been found that PtALD can catalyze the aldol condensation reaction of indolepyruvic acid with pyruvic acid (or oxalacetic acid) to yield 4-(indol-3-ylmethyl)-4-hydroxy-2-oxoglutaric acid (IHOG), and the reaction of phenylpyruvic acid with pyruvic acid to yield 4-phenylmethyl-4-hydroxy-2-oxoglutaric acid (PHOG).
