実験手順

0.13 g (0.38 mmol) of 4-hydroxy-4-(3-indolylmethyl)-2-hydroxyiminoglutaric acid ammonium salt was dissolved in 5 ml of aqueous 28% ammonia, to which 0.09 g of 5% rhodium carbon was added, for reaction at ambient temperature and a hydrogen pressure of 7.5 atmospheres. 14 hours later, the catalyst was filtered off, and the resulting solution was concentrated to dryness, to obtain a mixture of 0.075 g (0.23 mmol) of the ammonium salt of (2S, 4S)/(2R, 4R)-4-hydroxy-4-(3-indolylmethyl)-2-aminoglutaric acid (monatin) and 0.036 g (0.11 mmol) of the ammonium salt of (2S, 4R)/(2R, 4S)-4-hydroxy-4-(3-indolylmethyl)-2-aminoglutaric acid (monatin).
