conditions at room temperature using catalytic amount of Er(OTf)3. The catalyst is easily recovered from the aqueous phase and reused several times without significant loss of activity. The deprotection step developed is also highly eco-friendly since the tert-butyl group is removed very quickly from alcohols and phenols in methanol using MW irradiation. green chemistry - Lewis acid - protecting groups
提出了一种生态相容的方法,该方法允许形成或裂解醇和酚的叔丁基醚。该保护步骤在室温下在无溶剂条件下使用催化量的Er(OTf)3进行。催化剂易于从水相中回收并重复使用几次,而活性没有明显损失。所开发的脱保护步骤也是高度环保的,因为使用MW辐射可以非常快速地从甲醇中的醇和酚中去除叔丁基。 绿色化学-路易斯酸-保护基-叔丁基醚-微波加热
