Indole, and structures derived from it, are a component of many natural substances, such as the amino acid tryptophan. A new catalytic reaction produces cyclopenta[b]indoles -- frameworks made of ...

The indole nucleus is ubiquitous in natural products and pharmaceuticals, underpinning a broad spectrum of bioactive compounds. Traditional routes, notably the Fischer indole synthesis, remain ...

Indole and its derivatives constitute a foundational scaffold in both natural products and pharmaceutical chemistry, distinguished by a bicyclic system combining a benzene ring fused to a pyrrole ...
