Short step synthesis of 4-substituted indoles using palladium-catalyzed C-C bond forming reaction

Enol triflate of N-tosyl-4-oxo-tetrahydroindole (2) was a good precursor for a synthesis of 4-substituted indoles. Various functional groups were introduced to form corresponding indoles using palladium-catalyzed carbonylation and a cross-coupling reaction followed by dehydrogenation by palladium on charcoal.
