microwave‐irradiated alcohol‐protecting strategy based on gold catalysis utilizing benzyl alcohol, tert‐butyl alcohol and triphenylmethanol as alkylating reagents has been developed. This protecting strategy has wide functional group tolerance with satisfactory yields for the majority of the selected alcohols. The mechanism of this transformation was probed with oxygen‐18 isotope labelled alcohols assisted by
基于苄基醇,叔丁醇和三苯甲醇作为烷基化试剂的金催化的微波辐射醇保护策略已经被开发出来。对于大多数选定的醇,该保护策略具有宽泛的官能团耐受性和令人满意的产率。在GC-MS技术和化学动力学实验的辅助下,用氧18同位素标记的醇探索了这种转变的机理。该策略为有机合成中的苄基,叔丁基和三苯甲基醚的制备提供了一种有效,直接和替代的方法。
