Palladium-catalysed aminocarbonylation of 7-iodoindole derivatives (the parent compound and 5-bromo-7-iodoindole), as well as 5-iodoindole with various primary and secondary amines, including amino acid esters and chiral diamines, was carried out. In this way, a highly selective doublecarbonylation reaction at the C-7 was performed resulting in the formation of the corresponding indol-7-ylglyoxylamides
