  2-(Halomethyl)phenylacetic acid esters (3) which are useful as intermediates for producing agricultural fungicides are produced efficiently and conveniently by reacting a 3-isochromanone derivative (1) with a hydrogen halide and an alcohol or reacting (1) with a halomethyl alkyl ether and then reacting the product with an alcohol in the presence of a base. The starting compound, 3-isochromanone (1), is produced in good yield by reacting an α,α'-o-xylene dihalide (4) with carbon monoxide and water in an organic solvent in the presence of a palladium catalyst and an inorganic base and then treating the product with an acid.

  通过将 3-异色原酮衍生物 (1) 与卤化氢和醇反应，或将 (1) 与卤代甲基烷基醚反应，然后在碱存在下将产物与醇反应，可以高效、方便地生产出可用作生产农用杀菌剂中间体的 2-（卤代甲基）苯乙酸酯 (3)。在钯催化剂和无机碱存在下，在有机溶剂中使α,α'-邻二甲苯二卤化物（4）与一氧化碳和水反应，然后用酸处理产物，可以制得收率很高的起始化合物 3-异色酮 (1)。

  The present invention provides a composition that enables measurement of glycated hemoglobin in the presence of a stronger surfactant than conventional surfactants. To this end, the present invention provides an amadoriase in which one or more amino acids have been substituted at positions corresponding to positions selected from the group consisting of positions 80, 71, 175, 172, 279, 12, 9, 77, 30, 28, 13, 3, 4, 286, 204, 338, 44, 340, and 194 of the amadoriase derived from the genus Coniochaeta having the amino acid sequence as shown in SEQ ID NO: 1 as well as a composition for measurement of glycated hemoglobin comprising an amadoriase that retains activity in the presence of an anionic surfactant. The present invention can provide an enzyme and a composition for measurement of glycated hemoglobin that sufficiently remain stable even when exposed to anionic surfactants.

  本发明提供了一种组合物，该组合物能够在比传统表面活性剂更强的表面活性剂存在下测量糖化血红蛋白。为此，本发明提供了一种氨甲蝶呤酶，其中一个或多个氨基酸在与选自具有 SEQ ID NO：1 所示氨基酸序列的氨甲蝶呤酶，以及一种用于测量糖化血红蛋白的组合物，该组合物包含一种在阴离子表面活性剂存在下仍能保持活性的氨甲蝶呤酶。本发明可提供一种用于测量糖化血红蛋白的酶和组合物，即使暴露于阴离子表面活性剂中也能充分保持稳定。
