Murrayaquinone A is a carbazolequinone alkaloid isolated from the root bark of Murraya euchrestifolia Hayata. It has been found to exhibit cardiotonic activity on heart muscle. Starting from the commercially available 3-acylindole, the total synthesis of Murrayaquinone A was realized in eight steps in an overall yield of 8%. The key step of our synthesis involves a palladium-catalyzed intramolecular α-C-H alkenylation of indole derivative to construct the carbazole A ring.

Key words: murrayaquinone A, carbazole alkaloid, C-H alkenylation, total synthesis
