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
