路线

We prepared the pyrethric acid II through four reactions: esterification, oxidation, decomposition, diesterification. And the original synthesis route of the pyrethric acidII was improved: the yield of oxidation of allyl rise through increasing the activity of Selenium dioxide; in the document, tert-butyl-trans -2, 2-dimethy1-3-(2"-methoxycarbony1-1"-propenyl)cyclopropanecarboxy late was synthesized from tert-butyl-trans-2,2-dimethyl-3-(2 -formyl-r -propenyl) cyclopropanecarboxylate with two steps, with low yield.

我们经过酯化，氧化，成双酯，热分解四步反应，成功地得到了第二菊酸，并改进了原第二菊酸的合成路线：通过改变二氧化硒的活性提高了烯丙甲基的氧化产率；将原路线中醛氧化成羧酸、羧酸酯化的两步反应改为醛和甲醇、二氧化锰等作用一步直接酯化的方法，减少了反应步骤，提高了总收率。

Faced with getting from A to B, the average person will automatically set out on the best-known and apparently simplest route. The innovator will search for alternate courses, which may prove easier in the long run and are bound to be more interesting and challenging even if they lead to dead ends.

面对从A到B的问题，普通人会自动的选择简单的最为人知的路线，而创新者会寻找可以替代的路线，而这种发放被证明在长期来看可能是简单方便的，即使是不可行的死路一条，也是很有趣更有挑战意义的。
