A process for double deuterium labeling of an alcohol was developed. The process was utilized in the subsequent tritium labeling of a secondary alcohol with high specific activity (24 Ci/mmol) by reduction of the corresponding ketone using sodium borotritide. The starting ketone was first brominated with pyridinium tribromide; the resulting alpha bromoketone was then reduced in THF/alcohol in the presence of Ni(OAc)2. The alcohol was then converted to 2-amino-4-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid-[3H2], an mGluR agonist. Copyright © 2004 John Wiley & Sons, Ltd.
开发了一种醇的双氘标记工艺。通过使用三溴化硼钠还原相应的酮,该工艺被用于随后对具有高比活度(24 Ci/mmol)的仲醇进行氚标记。首先用三溴化吡啶鎓对起始酮进行溴化;然后在四氢呋喃/酒精中,在 Ni(OAc)2 的存在下还原得到α-溴酮。然后酒精被转化为 2-氨基-4-氟双环[3.1.0]己烷-2,6-二羧酸-[3H2],这是一种 mGluR 激动剂。Copyright © 2004 John Wiley & Sons, Ltd. All Rights Reserved.
