摘要
报道了一种用１．４－双甲氧甲基苯合成对甲氧甲基苄氯（Ⅰ）的较理想的方法及反式二氯菊酸拆分的方法．还报道了用（±）顺、反、（＋）反式、（－）反式二氯菊酸分与（Ⅰ）合成了相应的拟除虫菊脂Ⅱ、Ⅲ、Ⅳ，并对Ⅱ做了初步的药效试验．
This paper describs the synthesis of 4-CH3OCH2C6H4CH2Cl (Ⅰ ) from CH3OCH2C6H4CH2OCH3. The (+ ) trans-and trans (-) 2,2-dimethyl-3-(2',2'-dichloroethenyl ) cyclopropane carboxylic acid were obtained by resolution of the (± ) trans - acids. The (± )cis. trans, (+ ) trans, (-)trans-acids were esterifed respectively with (Ⅰ ) to geve the correspondent esters Ⅱ、Ⅲ、Ⅳ and the effective test of Ⅱ has been done.
