Indolecarboxamides are potent but poorly soluble mycobactericidal agents. Here we found that modifying the incipient scaffold by amide-amine substitution and replacing the indole ring with benzothiophene or benzoselenophene led to striking (10-20-fold) im

The addition of a carbene catalyst to an indole aryl aldehyde leads to the activation of a remote sp2 carbon that is five atoms away from the catalyst. The unsaturated Breslow intermediate formed between the catalyst and substrate undergoes an internal redox reaction and remote carbon protonation to generate an analogous azolium vinyl enolate intermediate. Subsequent [4+2] reaction with cyclic imine substrates eventually affords multicyclic pyridoindoles as nearly single diastereomers with excellent enantioselectivities.

We report a convenient synthesis of carbazole-1,4-quinone alkaloid koeniginequinones A and B using a tandem ring-closing metathesis with the dehydrogenation reaction sequence under an O2 atmosphere as an important step. Using this method, carbazole-1,4-quinones substituted at the 5-, 6-, 7-, and/or 8-positions have been synthesized. Moreover, 24 compounds, including koeniginequinones A and B, have been evaluated for their antiproliferative activity against HCT-116 and HL-60 cells, and the 6-nitro analog exhibited the most potent activity against both tumor cell types.
