実験手順

0.264 g (0.824 mmol) of 4-hydroxy-4-(3-indolylmethyl)-2-methoxyiminoglutaric acid was dissolved in 10 ml of aqueous 28% ammonia. 0.18 g of 5% rhodium carbon (dry product) was added and the mixture stirred at a hydrogen pressure of 7.5 atmospheres for 18 hours. The catalyst was filtered off and the solvent was distilled off under reduced pressure, to obtain the residue. The resulting residue was analyzed by NMR, and a mixture of 0.115 g (0.395 mmol; yield, 48%) of (2S, 4S)/(2R, 4R)-4-hydroxy-4-(3-indolylmethyl) -2-aminoglutaric acid (monatin) and 0.065 g (0.223 mmol; yield, 27%) of (2S, 4R)/(2R, 4S)-4-hydroxy-4-(3-indolylmethyl)-2-aminoglutaric acid was found to have been generated.
