一般描述

苄基溴是一种芳香卤化物,主要用作保护剂,通过 O-苄基化反应保护醇的羟基。

应用

苄基溴已被用作通过原子转移自由基聚合反应合成聚(苯乙烯-b-甲基丙烯酸甲酯)共聚物的引发剂。它可以与1,2-二甲基咪唑发生Menschutkin反应,形成3-苄基-1,2-二甲基咪唑鎓溴化物。

This paper reports the synthesis of (±)-licarin A 1, a dihydrobenzofuran neolignan, resultant of an oxidative coupling reaction of isoeugenol and horseradish peroxidase (HRP) enzyme. Following, three semi-synthetic derivatives from this compound were obtained: benzylated (±)-licarin A 2, methylated (±)-licarin
