The chemical synthesis of indoleterpenoids of structural and biological interests has attracted remarkable attention. Here we report an Eu(fod)3‐catalyzed indoleconjugateaddition reaction, which tolerates various acid‐sensitive functional groups. A collection of indoleterpenoidmimics have been prepared from natural product‐derived α,β‐unsaturated enones on the basis of this reaction. The further

We constructed a small library of indoleterpenoidmimics using a hybridizing strategy to link various indole and α,β‐unsaturated enone building blocks together. Prepared compounds were evaluated for the cytotoxicity against a panel of cancer cell lines. An indolyl ketone called JP18 was identified as a cellcycleregulator, and the underlying mechanism was investigated.

We have developed an intermolecularconjugateaddition of 3a‐pyrroloindoline/furoindolineradicals to α,β‐unsaturated enones, through visible‐light photoredox catalysis. Ir(ppy)2(dtbbpy) PF6 was found to be an effective promoter to initiate this reaction from readily available 3a‐bromopyrroloindolines/furoindolines. This method was exploited to prepare a series of indole terpenoid‐like compounds of

The present invention relates to compositions, for example, the DBU/Hexafluoroacetone hydrate salt, and processes of preparing and using the same for the modification of chemical compounds via the release of trifluoroacetate. The DBU/Hexafluoroacetone hydrate salt can perform trifluoromethylation reactions on chemical compounds, such as carbonyl group-containing compounds.
