Six new prenylated indole alkaloids, named notoamides F−K (8−13), were isolated from a marine-derived Aspergillus sp. Their structures, including absolute configurations, were elucidated by ...

An effective synthesis of the pentacyclic core of the unusual Kopsia alkaloid arboflorine is reported. The success of the synthetic route rested on the use of a borylative C–H functionalization ...

Further investigations revealed that the biosynthetic pathways of these complex chemical compounds have developed independently in the two species. ... saponins or monoterpenoid indole alkaloids.
