With hexaketocyclohexane octahydrate as the carbon monoxide source, a novel procedure for copper-catalyzed direct double carbonylation of indoles has been established. Using alcohols as reaction partners, moderate to good yields of the desired double carbonylation products have been obtained. Wide functional group tolerance and substrate scope can be observed.

indolylglyoxylamides are widely found in nature as alkaloids, and are important building blocks or synthetic intermediates for drug discovery, and for the synthesis of natural products. A careful inspection of the H NMR data of these molecules reveals that multiplicities for H4 and H7 are reported as broad doublets, as doublet of doublets-like, as a combination of doublet of doublets and multiplets, or simply as doublets
