This review highlights advances in isolation and synthesis of bis- and tris-indole alkaloids containing N-heterocyclic linker moieties. Natural products in this class are of particular significance due to their potent biological activities.
The CuI-catalyzed reaction between one 1,2-bis(2-bromoaryl)hydrazine moiety and two 1,3-diketones delivers substituted 1,1′-bisindoles with yields up to 92%.
This review focuses on fused-ring carbazole derivatives, their molecular design, electronic and photophysical properties, and their applications as the emitter and/or the host material in organic light emitting diodes (OLEDs).
This review discusses last decade's developments in carbazole synthesis. Aspects of selectivity and functional group tolerance are evaluated, as well as the applicability of such protocols towards the total synthesis of natural products.
Gold photocatalyst has been employed as sensitizer for the synthesis of cyclohepta[b]indoles. Substrate scope and limitations of the protocol are presented. Mechanistic studies indicate involvement of EnT-HAT mechanism.
