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 recently suggested theory of Pausacker and Schubert 1 involving free radicals in the Fischer indole synthesis appeared to us improbable. It seemed more likely that these experimental results could ...

More than 50 years after its discovery, the heterodimeric indole alkaloid haplophytine has yielded to total synthesis. Originally isolated from the dried leaves of a Mexican shrub, haplophytine is an ...

Powdered leaves from the Mexican cockroach plant, Haplophyton cimicidum, have been used to poison cockroaches and to repel fleas for hundreds of years. And attempts to synthesize one of the plant's ...
