FeCl3 Catalyzed Regioselective C-Alkylation of Indolylnitroalkenes with Amino Group Substituted Arenes
摘要:
An efficient FeCl3 catalyzed protocol for the synthesis of amino functionalized indolylnitroalkanes from easily available precursor indolylnitroalkenes and substituted amines has been developed. Regioselective C-alkylation in the presence of free amino substituted arenes occurred. The scope of this methodology shows good functional group tolerance, and further, this protocol was used to prepare indolylquinoline derivatives.
