Ring-14C-labelled 4(3′-, 6′-, dimethyl-3′-,heptyl)-phenol (NP), an isomer of paranonyl phenol was synthesized for use in aquatic toxicity and metabolism studies. A very efficient method involving alkylation of ring-14C-labelled anisole and tertiary alkyl bromide (3-bromo-3,6-dimethyl heptane) with AlCl3 followed by cleavage of the resultant ether with BBr3 was used giving a 24% yield ring labelled 14C-NP (specific activity: 16.205 MBq/mg and purity >95% by HPLC) after TLC separation.

环-14C-标记的4(3'、6'、二甲基-3'、庚基)-
苯酚(NP)是巴罗尼
苯酚的异构体,用于
水生
生物毒性和代谢研究。一种非常有效的方法是将环-14C-标记的
苯甲醚和叔烷基
溴化物(3-溴-
3,6-二甲基庚烷)与
AlCl3进行烷基化,然后用BBr3裂解生成的醚,经TLC分离后,环-14C-NP的产量为24%(比活度:16.205 MBq/mg,纯度>95%,HPLC)。版权所有 © 2001 John Wiley & Sons, Ltd.
