- Palladium(II)-catalyzed synthesis of the formylcarbazole alkaloids murrayaline A-C, 7-methoxymukonal, and 7-methoxy-o-methylmukonal
-
We describe the synthesis of the naturally occurring 2,7-dioxygenated formylcarbazole alkaloids 7-methoxymukonal, 7-methoxy-O-methylmukonal, and the murrayalines A-C. The carbazole framework was constructed by a Buchwald-Hartwig amination and a subsequent palladium(II)-catalyzed oxidative cyclization.
