The PtCl(2)-catalyzed reaction of 1-(indol-2-yl)-2,3-allenols occurred smoothly to form carbazoles by connecting the 3-carbon atom of indole with the 4-carbon atom of the allenol moiety, referring to the carbon atom connected to the hydroxyl group.

Insights to the subtle reactivity patterns of hydroxy-substituted carbazoles allows the precise synthesis of unsymmetrical azatrioxa[8]circulenes by the reaction of N-benzyl-2,7-di-tert-butyl-3,6-dihydroxycarbazole with two different 1,4-benzoquinones in the presence of an oxidant (chloranil) and a Lewis acid (BF3OEt2). The unique synthetic control obtained originates from the selectivity obtai...

Aromatic dicationic compounds possess antimicrobial activity against a wide range of eucaryotic pathogens, and in the present study an examination of the structures-functions of a series of compounds against fungi was performed. Sixty-seven dicationic molecules were screened for their inhibitory and fungicidal activities against Candida albicans and Cryptococcus neoformans. The MICs of a large ...

Conducting polymers such as polycarbazole and its derivatives have attracted much attention due to their remarkable electrical optical properties. To prepare derivatives, a variety of substituents can be added the nitrogen atom carbazole monomers or 3- 6-positions. In present study, bearing hydrogen, methyl benzyl group at N-position styryl (naphthalen-1- -2-yl)vinyl 3-position were synthesized...

The heterocyclic analogs of o-quinodimethane (OQDM, o-xylylene) are of considerable interest both from a theoretical point of view and for their potential in organic synthesis 1 as useful dienes. This has been elegantly demonstrated in the indole series 2 for the synthesis of several naturally occurring and biologically important indole 3 and carbazole 4 alkaloids. However, with the exception o...

The impact of the hoop size on electronic and charge transport properties [5]- [4]-cyclo-N-butyl-2,7-carbazoles is reported. In these examples, a small nanohoop beneficial for good organization molecules into thin films, whereas large one increases density structural defects. More information can be found in Research Article by C. Poriel co-workers (DOI: 10.1002/chem.202300934).
