Abstract: An efficient RhIII‐catalyzed direct C2‐alkenylation of indoles using readily available potassium vinyltrifluoroborate under mild conditions has been developed. This protocol features wide substrate scope and excellent functional group compatibility, enabling a facile access to diverse terminal vinylindoles in moderate to good yields. Furthermore, the C2‐alkenylated indole can be easily transformed into 9H‐carbazole through a ring‐closing metathesis/aromatization cascade. [ABSTRACT FROM AUTHOR]

A simple and versatile method for highly efficient synthesis of various polysubstituted indoles via a sequential one-pot Rh(III)-catalyzed direct C2–H and C7–H alkylation with diazo compounds has been developed. This process features with mild reaction conditions, wide substrate scope, and good functional group tolerance (24 examples, up to 96% yield). [ABSTRACT FROM AUTHOR]

A highly efficient Rh(III)-catalyzed direct C–H arylation of indoles with aryl boronic acids under mild conditions has been developed. The methodology features wide substrate scope and excellent functional group compatibility (34 examples, up to 99% yield). The arylated products can also be conveniently transformed into biologically active polycyclic indole derivatives. [ABSTRACT FROM AUTHOR]
