  Development of an Enzyme-Linked Immunosorbent Assay for the Detection of the Pyrethroid Insecticide Fenpropathrin

  摘要：

  A competitive enzyme-linked immunosorbent assay (ELISA) was developed for the quantitative detection of fenpropathrin [(RS)-alpha-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropanecarboxylate]. Polyclonal antisera were isolated from rabbits immunized with two different fenpropathrin hapten conjugates. One hapten contained an amino function; the other contained a carboxyl group for conjugation to carrier proteins. Mollusk hemocyanins, thyroglobulin, and fetuin were used as carrier proteins. The antisera varied greatly in their affinities for fenpropathrin. A homologous assay system using the coating antigen format was the most sensitive. The IC50 for fenpropathrin was 20 mu g/L, and the lower detection limit was 2.5 mu g/L. Pyrethroids, such as phenothrin, permethrin, resmethrin, fenvalerate, deltamethrin, cyfluthrin, and cypermethrin, and the pyrethroid metabolites, 3-phenoxybenzoic acid and fenpropathrin acid, did not cross-react significantly in this assay. Ten percent acetone or methanol and a pH of 4 were determined to be optimum assay conditions. Various cationic, anionic, and nonionic detergents had no significant effect on the assay.

  酸催化的1,3-二取代的四氢吡喃并[3,4- b ]吲哚的高非对映选择性和有效合成

  摘要：

  我们首次成功地探索了三氟乙酸（TFA）可以有效催化次要色酚和缩醛的oxa-Pictet-Spengler反应，以合成1,3-二取代的1,3,4,9-四氢吡喃[3,4- b吲哚类化合物的产率高（高达> 99％）和非对映选择性（> 20：1）。由吲哚-3-乙酸合成仲三酚。由二级p酚和由醛和原甲酸三甲酯原位制备的缩醛成功开发了一锅合成四氢吡喃并[3,4- b ]吲哚，从而有效地提高了该方案的成本效率。最后，催化不对称合成1,3-二取代的四氢吡喃[3,4- b在高度对映体纯的次要三甲基酚的对映选择性实现后，也证明了]吲哚。
