A biomimetic method to synthesise indolo[3,2-a]carbazoles
摘要:
A simple and biomimetic synthetic strategy for indolo[3,2-a]carbazoles has been developed. Our approach involved the efficient conversion of 2-(3'-indolyl)tryptophan derivatives into the corresponding cc-keto esters and the subsequent aromatic cyclisation of these intermediates to construct the characteristic heteroaryl-condensed carbazole core.

Diacylimidazolium ions yield adducts with aromatic compounds. Thus the N,N'-diacetylimidazolium ion and indole gives 1,3-diacetyl-2-(3-indolyl)-4-imidazoline. Less reactive substrates such as thiophene, anisole and 1,3-dimethylbenzene fail to react with this reagent but do form adducts (e.g. 1,3-bis-(trifluoroacetyl)-2-(2-thienyl)-4-imidazoline) with an imidazole/trifluoroacetic anhydride reagent.
The invention relates to compounds which are suitable for use in electronic devices, and to electronic devices, in particular organic electroluminescent devices, containing said compounds.
