An efficient and selective synthesis of 3-acetyl free(N-H)/N-substituded indoles and 3-acetoacetyl free(N-H)/N-substituded indoles has been developed via the hydrolysis reaction of β-ethylthio-β-indoly α, β-unsaturated ketones in the presence of 3 equivalent of NaOH and 5 mol% of H2SO4, respectively. The procedure features easy operation, excellent yields, and high selectivity, compatibility and practicability.
Rh(III)-Catalyzed [5 + 1] Annulation of Indole-enaminones with Diazo Compounds to Form Highly Functionalized Carbazoles

A novel Rh(III)-catalyzed C-H activation/annulation cascade of indole-enaminones with diazo compounds was reported to construct diversely functionalized carbazole frameworks. The most notable characteristic is that this transformation could smoothly furnish a novel [5 + 1] cyclization product with good to excellent yields (up to 95%), accompanied by the thorough removal of acetyl and N,N-dimethyl groups of two substrates from the target products, rather than the normally expected [4 + 2] cyclization products.

A novel method for the Rh(III)-catalyzed oxime-directed C-H amidation of indoles with dioxazolones has been developed. This strategy provides an exclusive site selectivity and the directing group can be easily removed. This transformation features a wide substrate scope, good functional group tolerance and excellent yields, and may serve as a significant tool to construct structurally diverse indole derivatives for the screening of potential pharmaceuticals in the future.
