Abstract:
A unified modular synthetic strategy has been developed for 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 in situ. Several dictyodendrin analogues were also synthesized using this strategy.
