OBJECTIVE:To obtain high purified and cheap human copper/zine superoxide dismutase with genetic engineering and affinity chromatography.

目的：用基因工程的方法获得人铜锌超氧化物歧化酶的高产菌，通过发酵培养，最后纯化获得大量廉价的高纯度的hCu，Zn－SOD。

This paper details an efficient method for a one-step transformation of the trityl ether to the acetonide. Treatment of trityl ether with a mixture of trifluoroacetic acid, 2,2-dimethoxy propane and camphorsulfonic acid as catalyst in dichloromethane through detritylation followed by acetonization gave the acetonide in high yield.

介绍了一种新的高效的由三苯甲基醚直接生成丙酮化合物的方法，也就是使三氟乙酸条件下脱三苯甲基的反应和生成丙酮化合物的反应在一个反应瓶中同时进行，使脱三苯甲基作用后生成的醇继续反应得到高产率的丙酮化合物。
