(E)- and (Z)-2,3-methano-m-tyrosines (9E and 9Z) have been synthesized from a common intermediate, monoester (Z)-1-(ethoxycarbonyl)-2-[3-[(2-methoxyethoxy)methoxy]phenyl] cyclopropanecarboxylic acid (5). Quinine and ephedrine, respectively, were used to resolve their N-tert-butoxycarbonyl (Boc) derivatives. Among the compounds prepared, the (+)-(E)-diastereomer of 9 is the most potent inhibitor of
外消旋的(E)-和(Z)-2,3-甲基-间-酪氨酸(9E和9Z)都是由一种常见的中间体单酯(Z)-1-(乙氧羰基)-2- [3- [ (2-甲氧基乙氧基)甲氧基]苯基]环丙烷羧酸(5)。奎宁和麻黄碱分别用于拆分其N-叔丁氧羰基(Boc)衍生物。在制备的化合物中,9的(+)-(E)-非对映异构体是L-芳族氨基酸脱羧酶(Dopa脱羧酶)最有效的抑制剂,Ki为22 microM,而(-)-Z-非对映异构体(9Z)秒,Ki = 49 microM。(+)-9E是DDC的强效抑制剂,比其无环类似物Dm-酪氨酸强45倍。
