Reaction Steps

380 mg (1.31 mmols) of 5-(RS)-(3-indolylmethyl)-4,5-dihydroisoxazole-3,5-dicarboxylic acid was dissolved in 8 ml of 28% aqueous ammonia solution, 200 mg of a 5% rhodium-active carbon catalyst was added thereto, and catalytic hydrogenation was conducted under a hydrogen pressure of 1 MPa for 16 hours. The catalyst was removed by filtration, and the filtrate was freeze-dried to obtain 336 mg of monatin and a small amount of DL-alanine as a by-product.
