  Phenyl β-Methoxyacrylates:  A New Antimalarial Pharmacophore

  摘要：

  Phenyl beta-methoxyacrylates, linked to an aromatic ring via an olefinic bridge, have been identified as novel, potentially inexpensive, antimalarial agents. The compounds are believed to exert their activity by inhibition of mitochondrial electron transport at the cytochrome bc(1) complex. A series of compounds have been synthesized to define structure-activity relationships affecting antimalarial activity. It was found that the beta-methoxyacrylate was required ortho to the linker and the optimal bridge was (E,E)-butadiene, Compounds in which the second aromatic ring was ortho-substituted or ortho,para-disubstituted gave optimal potency. Several compounds were identified with potency that is superior to that of chloroquine both in culture and in a murine malaria model.

  烷基形式的α-杂原子取代的乙酸酯的脱水型Ti-Claisen缩合（碳同位）：作为（Z）-立体定义的交叉偶合剂的用途及其在Strobilurin A的简捷合成中的应用

  摘要：

  的TiCl 4 -Et 3 Ñ或-Bu 3 ñ试剂进行的高度（ż烷基α-杂原子（卤和磺酰氧基）的）-stereoselective碳同系化（脱水型Ti克莱森缩合）取代的乙酸盐（XCH 2 CO 2 R）用烷基甲酸酯（HCO 2 R）得到各种烷基β-烷氧基-α-卤代或磺酰氧基取代的丙烯酸酯（24个实例； 51％–91％的收率）。使用获得的甲基β-甲氧基-α-卤代或磺酰氧基取代的丙烯酸酯的立体定向Suzuki-Miyaura，Negishi和Sonogashira交叉偶联反应顺利进行，以中等至高收率生产了多种β-烷氧基-α-取代的丙烯酸酯（35实例； 29％–99％的收率）。作为一项成功的应用，利用本发明的反应顺序（脱水型Ti-Claisen缩合和Suzuki-Miyaura交叉偶联）进行了3步直接合成的strobilurin A的合成，其中三个连续烯烃的几何构型（2 E，3 Z，5 E）被完全维持。
