I found the field of Chemistry very interesting. Saw the article B(C6F5)(3)-Catalyzed Direct C3 Alkylation of Indoles and Oxindoles published in 2020. Application In Synthesis of Indolin-2-one, Reprint Addresses Melen, RL; Morrill, LC (corresponding author), Cardiff Univ, Sch Chem, Cardiff Catalysis Inst, Cardiff CF10 3AT, Wales.; Pulis, AP (corresponding author), Univ Leicester, Sch Chem, Leicester LE1 7RH, Leics, England.. The CAS is 59-48-3. Through research, I have a further understanding and discovery of Indolin-2-one
The direct C3 alkylation of indoles and oxindoles is a challenging transformation, and only a few direct methods exist. Utilizing the underexplored ability of triaryl boranes to mediate the heterolytic cleavage of alpha-nitrogen C-H bonds in amines, we have developed a catalytic approach for the direct C3 alkylation of a wide range of indoles and oxindoles using amine-based alkylating agents. We also employed this borane-catalyzed strategy in an alkylation-ring opening cascade.
