  日期：2010.7.30

  A series of novel α-amino phosphonate derivatives containing the thiazole and pyrazole moieties 3 were synthesized by the Mannich-type reaction of substituted pyrazole-aldehyde 1, 2-amino-5-ethoxycarbonyl-4-methyl-thiazole 2, and dialkyl phosphites or triphenyl phosphite in the presence of a Lewis acid such as magnesium perchlorate as the catalyst under solvent-free conditions. Their structures were

  通过取代吡唑醛 1、2-氨基-5-乙氧羰基-4-甲基-噻唑 2 和亚磷酸二烷基酯的曼尼希型反应合成了一系列含有噻唑和吡唑部分 3 的新型 α-氨基膦酸酯衍生物。在无溶剂条件下，在路易斯酸（如高氯酸镁）作为催化剂存在下，亚磷酸三苯酯。它们的结构通过光谱数据（IR、1H NMR、31P NMR、MS）和元素分析得到了明确证实。初步生物测定（体外）的结果表明，某些标题化合物 3 在 100 mg/L 时对双子叶植物（Brassica campestris L）或单子叶植物（Echinochloa crus-galli）具有中等除草活性。补充材料可用于本文。去出版商'
