To study the metabolism of minor conjugated linoleic acid isomers (CLAs), (7E,9Z)-[9,10-2H] CLA was prepared in three steps from a conjugated enyne precursor. In the labelling step, deuterium atoms were introduced by partial reduction of the triple bond using deuterated disiamylborane and acetic acid-d4. Deuterated (7E,9Z) CLA was obtained with high isotopic enrichment (>99%) and purity greater than 95%. Copyright © 2004 John Wiley & Sons, Ltd.
为了研究次要共轭亚油酸异构体(CLA)的新陈代谢,我们从共轭炔烃前体出发,分三步制备了(7E,9Z)-[9,10-2H] CLA。在标记步骤中,使用氘化二二甲基硼烷和乙酸-d4 通过部分还原三键引入氘原子。得到的氘代 (7E,9Z) CLA 同位素富集度高(大于 99%),纯度大于 95%。Copyright © 2004 John Wiley & Sons, Ltd. All Rights Reserved.
