氯乙酸

Phenyl or m -tolyl selenoamides reacted with functionalized α-haloacetic acid in 1∶1 or 1∶2 molar ratio with no catalyst in various alcohols to undergo a selenium transfer reaction. This reaction in dif-ferent molar ratios furnished the same C—Se—Se—C coupling products with a special structure bis diselenide. A new and facile method for synthesis of such bis(alkoxycarbonyl-methyl) diselenides with the advantages of mild reaction conditions, high yields, easy availability of starting materials and good chemical selectivity was provided.

以三甲胺及一氯乙酸为原料合成甜菜碱。

In order to explore the extraction method of proteome and technique of 2-DE, we compared the extraction method between the TCA-ac-tone and the Tris-HCl, and improved the key steps of 2-DE. The Tris-HCl extraction was the most appropriate for Antiaris toxicaria seed proteome analysis because of the highest resolution and more informative 2-DE map. Those were the solid basis for the later research of studying on the discrepancy expression proteomics of Antiaris toxicaria Seed.
