Indole, a molecule made up of a six-membered benzene ring fused to a five-membered ring containing nitrogen, forms the core structure of many biologically active compounds. Derivatives of indole, ...

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 ...

Gas chromatography-mass spectrometric analyses of purified extracts from cultures of Rhizobium phaseoli wild-type strain 8002, grown in a non-tryptophan-supplemented liquid medium, demonstrated the ...

Indole terpenes have attracted the interests of synthetic chemists due to their complex architectures and potent biological activities. Examples of total syntheses of several indole terpenes were ...
