designed fluorene-based mono- and bimetallic Pd–PEPPSI complexes were synthesized and demonstrated to be effective for the one-pot sequential α-arylation/alkylation of oxindoles. This streamlined approach offers efficient access to functionalized 3,3-disubstituted oxindoles in excellent yields (up to 89%) under mild reaction conditions.
合成了合理设计的基于芴的单金属和双金属Pd-PEPPSI配合物,并证明了对一锅顺序的吲哚α-芳基化/烷基化反应有效。这种简化的方法可在温和的反应条件下以优异的收率(高达89%)有效地获得官能化的3,3-二取代的羟吲哚。
