4, 5 and aminothiazole 6, 7 kainoid analogues were efficiently synthesised in five steps from commercially available (-)-alpha-kainic acid I and exhibited strong binding to the kainate receptors. A reactive alpha-bromoketone 10 was generated and reacted with thioamides and thioureas to form thiazole and aminothiazole heterocycles 11-14. Deprotection gave the new kainoid amino acids 4-7 in excellent
新的C-4噻唑4、5和氨基噻唑6、7类海因类似物可从市售的(-)-α-海藻酸I中分五步有效合成,并与海藻酸酯受体牢固结合。生成反应性的α-溴酮10,并使其与硫酰胺和硫脲反应形成噻唑和氨基噻唑杂环11-14。脱保护以优异的产率得到了新的类胡萝卜素氨基酸4-7。
