Enantiomerically pure pyrrolidine-2,4-diones (tetramic acids) which can be diastereoselectively hydrogenated to syn-statines (4-amino-3-hydroxy-6-methylheptanoic acids) have been prepared by catalytic hydrogenation of 4-(benzyloxycarbonylamino)-3-oxocarboxylic acid esters.
通过催化 4-(苄氧羰基氨基)-3-氧代羧酸酯的氢化反应,制备出了对映体纯的吡咯烷-2,4-二酮(四元酸),它可以非对映选择性地氢化为 syn-statines(4-氨基-3-羟基-6-甲基庚酸)。
