  Excitatory amino-acid receptor agonists. Synthesis and pharmacology of analogues of 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid

  摘要：

  We have previously proposed the existence of a lipophilic cavity of the 2-amino-3-(3-hydroxy-5-methylisoxazol4-yl)propionic acid (AMPA) receptor recognition site capable of accommodating alkyl substituents of limited size in the 5-position of the isoxazole ring. In order to indirectly elucidate the approximate extent of this proposed cavity we have synthesized and pharmacologically characterized a number of AMPA analogues. For most of these AMPA analogues, a positive correlation between AMPA receptor affinity and agonist effect was observed. The only exception was demethyl-AMPA (8a), which showed relatively high AMPA receptor affinity (IC50 = 0.27 mu M) but remarkably weak agonist potency (EC50 = 900 mu M). Whereas the ethyl analogue of AMPA (Et-AMPA) (IC50 = 0.030 mu M; EC50 = 2.3 mu M) has previously been shown to be slightly more potent than AMPA (IC50 = 0.040 mu M; EC50 = 3.5 mu M), substitutions of a propyl or a butyl group for the methyl group of AMPA to give 8b (IC50 = 0.090 mu M; EC50 = 5.0 mu M) or 8f (IC50 = 1.0 mu M; EC50 = 32 mu M), respectively, result in progressive loss of the AMPA agonist effect. Analogues containing larger groups, such as isopentyl (8e), 1-propylbutyl (8g), 2,2-dimethylpropyl (8h), or benzyl (14) groups, were very weak or totally inactive as AMPA receptor ligands.

  Asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate with sodium salt of acetamidomalonate ester has been carried out in the presence of a palladium catalyst containing (S)-BINAP to give a chiral α-allyl-αacetamidomalonate ester derivative of high optical purity (94±1% ee).

  在含有（S）-BINAP的钯催化剂的存在下，已将1,3-二苯基-2-丙烯基乙酸乙酸酯与乙酰氨基丙酸酯的钠盐进行不对称烯丙基烷基化反应，得到高光学纯度（94±1％ee）。

  Chiral bisoxazolylphosphine ligands 1 [(S,S)-PhP(Ox-R)(2): R = Me, Pr-i, Bu-t] with an N-P-N backbone were prepared from chiral 4-alkyl-2-phenyl-4,5-dihydrooxazole compounds. These ligands coordinated to Pd(II) ion as bidentate ligands selectively to give a stereogenic phosphorus atom. The Pd-(S,S)-PhP(Ox-Bu-t)(2) 1c catalyst evoked high enantioselectivity in asymmetric allylic substitutions of acyclic substrates using dimethyl sodiomalonate as nucleophile. In the reaction of 3-penten-2-yl acetate, which affords a pi-allyl intermediate with a small steric factor, the Pd-1c catalyst successfully induced very high enantioselectivity (94% ee) indicating the effectiveness of the P-stereogenic center formed by selective ligation of ligand 1. In the reaction of cyclic substrates, moderate to high enantioselectivity was obtained by Pd-1 catalyst using the sodium salt of dimethyl methylmalonate. (C) 2003 Elsevier Ltd. All rights reserved.
