enols/ketones has been achieved using either Hendrickson reagent in combination with triflic anhydride or triflic acid, which provides an efficient protocol for the divergent synthesis of polysubstituted indoles with flexible substituent patterns from α-arylamino-β-hydroxy-2-enamides, α-arylamino-β-oxo-amides or their enol-keto tautomeric mixture.
使用 Hendrickson 试剂结合三氟甲磺酸酐或三氟甲磺酸实现了酰胺和烯醇/酮的化学选择性亲电活化,这为从 α -芳基氨基 - β - 羟基 - 发散合成具有灵活取代基模式的多取代吲哚提供了有效的方案2-烯酰胺、α-芳基氨基-β-氧代-酰胺或它们的烯醇-酮互变异构混合物。
