Six phenylalanine analogues containing 2′-methyl-, 2′,6′-dimethyl-, 2′-ethyl-6′-methyl-, 2′-isopropyl-6′-methyl-, 2′,4′,6′-trimethyl-, and 3′,5′-dimethyl-L-phenylalanine were synthesized enantioselectively through asymmetric hydrogenation of acetamidoacrylate derivatives. Enzymatic digestion and X-ray analysis supported the L-configuration of the phenylalanine derivatives obtained.
通过不对称氢化乙酰氨基丙烯酸酯衍生物,立体选择性地合成了六种含有2′-甲基-、2′,6′-二甲基-、2′-乙基-6′-甲基-、2′-异丙基-6′-甲基-、2′,4′,6′-三甲基-和3′,5′-二甲基-L-苯丙氨酸的苯丙氨酸类似物。酶解和X射线分析证实了所获得的苯丙氨酸衍生物的L构型。
