introduce benzylsulfonyl (Bns) as a valuable protecting group in phenol chemistry. Bns proved to be stable under drastic reaction conditions and towards many common reagents. The deprotection proceeds quantitatively using catalytic hydrogenolysis. Additionally the Bns deactivating properties make this protecting group useful for tuning the reactivity of phenolic substrates.
我们引入苄基磺酰基(Bns)作为苯酚化学中的宝贵保护基。事实证明,Bns在激烈的反应条件下和对许多常用试剂都稳定。使用催化氢解定量地进行脱保护。另外,Bns失活特性使该保护基团可用于调节酚醛底物的反应性。
