simple, atom economical, highly efficient and green protocol has been developed for the SN1-type substitutions of 9H-xanthen-9-ol with indoles or other nucleophiles (such as diketone and pyrrole). This approach provides the substitution products in high or excellent yields in the BmimBF4 media at roomtemperature.
已经开发出一种简单,原子经济,高效且绿色的方案,用于用吲哚或其他亲核试剂(例如二酮和吡咯)将9 H-黄嘌呤-9-ol进行S N 1型取代。在室温下,该方法可在BmimBF 4培养基中以高收率或优异的收率提供替代产品。
