    A Concise, Stereocontrolled Thiazolium Ylide Approach to Kainic Acid
    摘要:
    Racemic alpha-kainic acid (1) has been prepared from (1SR,2SR,5RS)-ethyl (N-(benzyloxycarbonyl)3-aza-6-oxobicyclo[3.3.0] octane-2-carboxylate (11) in ca. 16% overall yield via a concise six-step synthetic sequence. Compound 11 is prepared pn a large scale in 50% yield via the [3 + 2] cycloaddition of thiazolium ylide 9 and 2-cyclopentenone, which provides the requisite 2,3-trans, 3,4-cis stereochemical array about the trisubstituted pyrrolidine nucleus in 1. Chemoselective addition of the one-to-one adduct of MeLi and TiCl4 to the ketone functionality in 11 followed by dehydration, oxidative ring opening, and nonbasic methylenation of the stereochemically labile C4 acetate moiety with CH2I2-Zn-TiCl4 affords the fully protected penultimate intermediate 17 which is exhaustively hydrolyzed to provide 1. This represents a highly efficient and stereocontrolled preparation of (+/-)-alpha-kainic acid.

    receptors. Substitution of phenyl for the methyl at the C-4 position of kainic acid produced 11 which has high affinity and agonist potency at the GluR6 receptor. Substitution on phenyl led to a series of compounds with varying affinity for this kainate receptor. Agonist potency correlated with receptor affinity and with no derivative could antagonist activity be identified. Affinities for the humGluR6 kainate
    描述了一系列新的4-芳基取代的海藻酸类似物的合成和药理学表征。确定了重组表达的humGluR6海藻酸酯受体的亲和力,以及[3H]海藻酸酯与大鼠前脑海藻酸酯受体的结合力。使用表达humGluR6受体的细胞中的全细胞电压钳记录评估功能性激动剂的效力。在海藻酸的C-4位上用苯基取代甲基可制得11,它在GluR6受体上具有很高的亲和力和激动剂效力。在苯基上的取代产生了一系列对该海藻酸酯受体具有不同亲和力的化合物。激动剂效力与受体亲和力相关,并且没有衍生物可以鉴定出拮抗剂活性。humGluR6海藻酸酯受体的亲和力比在大鼠前脑海藻酸酯受体上观察到的亲和力小约10-50。此外,在一系列的4-芳基取代的海藻酸类似物中,对于humGluR6受体的结合亲和力与与海藻酸盐的竞争与大鼠前脑海藻酸盐受体的结合之间存在高度相关性。

    As part of a medicinal chemistry collaboration, a number of novel bi- and tricyclic alpha-amino acids were prepared through various routes and characterized by H-1 nuclear Overhauser effect difference experiments. The syntheses provide a number of routes to access some highly substituted amino acid derivatives that have not been reported previously. It is envisaged that the chemistry described here could be applied to the synthesis of other unique substrates.
