The invention relates to a coupled enzymatic process for producing tryptamine derivatives from indole compounds. In the first enzyme-catalyzed reaction, indole derivatives are converted to tryptophan derivative intermediates, then the tryptophan intermediates are decarboxylated in a second enzymatic reaction in the same reaction system. In this way, tryptamine derivative products are formed from indole derivatives in a single process. The invention is also directed to novel tryptophan and tryptamine derivatives, which can be prepared by the inventive method.
