Microwave assisted Leimgruber-Batcho reaction for the preparation of indoles, azaindoles and pyrroylquinolines

The development of enhanced conditions for Lewis acid catalysed Leimgruber-Batcho indole synthesis using microwave acceleration is described. This approach has permitted the preparation of a variety of heteroaromatic enamine intermediates in good yield and high purities. Subsequent catalytic hydrogenation reactions, under various conditions including the use of a solid-phase encapsulated catalyst, furnish the corresponding indole derivatives in good yields.

Novel tryptophan dioxygenase inhibitors and combined tryptophan dioxygenase/5-HT reuptake inhibitors

Tryptophan dioxygenase (TDO) is a liver enzyme that is responsible for the majority of the metabolism of tryptophan. A series of novel 3-(2-pyridylethenyl)indoles are shown to be potent inhibitors of TDO with selected members of the series also having 5-hydroxy tryptamine (5-HT) reuptake inhibitory activity. These compounds are shown to provide significant increases in the levels of tryptophan and 5-HT in the cerebrospinal fluid and are thus of interest for antidepressant therapy.
