the first total synthesis of dictyodendrins G and synthesis of dictyodendrin F, H and I in 11 steps. The synthesis features consecutive functionalization of the core aminoquinone by palladium-mediated Suzuki–Miyaura coupling reaction, 1,4-addition, acylation and base mediated formation of a pyrrolinone, and the formation of carbazolequinone moiety through a formal [3 + 2] cycloaddition using arynes generated
