Abstract: Abstract The FeCl3-catalyzed cross-coupling through a sequential C−N and C−C bond-forming via tandem C−H and N−H bonds functionalization represents a novel method for the formation of dimeric carbazole derivatives. This approach provides a novel dimeric… read more here.

DOI: 10.1055/s-0040-1706551
Abstract: We describe the first total synthesis of the recently discovered pyrano[3,2-a]carbazole alkaloid clausenalansine A. The synthetic strategy for the construction of this formylpyrano[3,2-a]carbazole is based on a sequence of Buchwald–Hartwig coupling, palladium(II)-catalyzed oxidative cyclization, Lewis… read more here.
