was also eliminated by the addition of 2 equivalents of water to the reaction system. The reduction was applied to the syntheses of precursors of such anti-inflammatory agents as ibuprofen, butibufen, naproxen, and related compounds, as well as (±)-ar-turmerone, an odorous sesquiterpene.
在室温下,用 6 当量的 Me3SiCl-NaI-MeCN 试剂在己烷中处理,可以还原去除苄基位置的仲羟基和叔羟基。通过向反应体系中加入2当量的水也消除了苄基三甲基甲硅烷氧基。这种还原作用适用于诸如布洛芬、布布芬、萘普生和相关化合物以及 (±)-ar-turmerone(一种有气味的倍半萜烯)等抗炎剂前体的合成。
