In support of a program to develop a treatment for depression, four labeled forms of a delta opioid agonist were prepared. The [2H4] labeled form was prepared using a relatively straightforward conversion of [2H4]bromoethanol to [2H4]N-methyl-2-hydroxyethylamine. The key step in the synthesis of the [2H6] labeled form involved the Pd-catalyzed exchange in D2O of 8-quinolin-8-ol to give [2H6] 8-quinolin-8-ol. The C-14 labeled form was synthesized in one step using [14C]carbonylation, and the C-11 labeled form was prepared in two steps from 11CH3I. Copyright © 2011 John Wiley & Sons, Ltd.
为了支持开发抑郁症治疗方案,制备了四种标记形式的δ阿片激动剂。其中,[2H4]标记形式是通过相对简单的转化,将[2H4]溴乙醇转化为[2H4]N-甲基-2-羟基乙胺。合成[2H6]标记形式的关键步骤是利用钯催化剂在D2O中对8-喹啉-8-醇进行交换,从而得到[2H6] 8-喹啉-8-醇。C-14标记形式是通过[14C]羰基化在一步中合成的,而C-11标记形式则是通过11CH3I进行两步合成的。版权 © 2011 John Wiley & Sons, Ltd.
