Abstract
[reaction: see text] For the first time, palladium-catalyzed carbonylations of unprotected bromoindoles have been performed successfully with different N- and O-nucleophiles. Various indole carboxylic acid derivatives are accessible in excellent yield. For example, aminocarbonylation of 4-, 5-, 6-, or 7-bromoindole with arylethylpiperazines provides a direct one-step synthesis for CNS active amphetamine derivatives.
