Abstract Aqueous methanolic potassium carbonate under reflux has been demonstrated to be a highly effective deprotective agent for the tert‐butyl carbamates of indoles, indazoles, carbazole, thiazoloindole, and pyrrole. The method is a mild one and is particularly expeditious for NH‐heteroarenes bearing electron‐withdrawing groups.
摘要 回流下的甲醇碳酸钾水溶液已被证明是吲哚、吲唑、咔唑、噻唑并吲哚和吡咯的氨基甲酸叔丁酯的高效脱保护剂。该方法是一种温和的方法,尤其适用于带有吸电子基团的 NH-杂芳烃。
