求助一段漢語(yǔ)翻譯成英語(yǔ)

求下段漢語(yǔ)翻譯成英語(yǔ),不要在google上翻譯的,希望高手幫忙好好翻譯一下。謝謝啦! A類(lèi)化合物是一類(lèi)具有多樣的藥物活性和生物活性的化學(xué)物質(zhì)。目前,對(duì)A類(lèi)化合物的研究已經(jīng)成為天然產(chǎn)物化學(xué)合成中的重要內(nèi)容。 本文的主要論述了通過(guò)一種新穎的利用無(wú)機(jī)鹽催化一步高效合成a的方法構(gòu)建一系列的具有抗氧化活性的B化合物。此外,本文的另一個(gè)創(chuàng)新點(diǎn)是合成含有C基團(tuán)的二B化合物,由于C基團(tuán)本身便具有很好的抗氧化性能,那么我們預(yù)測(cè)終產(chǎn)物將具有更好的抗氧化活性。 在此立題思想下,本文設(shè)計(jì)了相應(yīng)的合成路線并從簡(jiǎn)單的原料出發(fā)最終合成了B終產(chǎn)物。與此同時(shí),還完成了合成C的前期工作成功的合成了D。 |

A compounds is a sort of chemical (that is) possessed of a variety of pharmaceutic and biologic activity. At precent, studying on A compounds become the prime task of syntheses of nature drugs. In this paper, an efficient method of one-pot synthesis of A by using a novel inorganic salt catalyst was mainly discoursed, and thus a series of B compounds with inoxidability were synthesised. Besides, a new idea was put forward to prepare di-B compounds with C-group. The inoxidability of final products were predicted due to the strong inoxidability of C-group. Corresponding synthetic scheme was designed to prepare the final products B from simple raw materials. Whereas, the first-phase preparations of the synthesis of C was made, and compound(s) D was prepared successfully. |
