Total synthesis of (-)-flustramine B via one-pot intramolecular ullmann coupling and claisen rearrangement

Total synthesis of (-)-flustramine B was achieved via one-pot intramolecular Ullmann coupling and Claisen rearrangement. A striking feature of this method of synthesis is that the sequential intramolecular Ullmann coupling and Claisen rearrangement reactions proceeds with concomitant deprotection of the methoxymethyl (MOM) group to afford spirocyclic oxindole with perfect asymmetric transmission in good overall yield.

Synthesis of indoloquinolines: An intramolecular cyclization leading to advanced perophoramidine-relevant intermediates

The bioactive natural product perophoramidine has proved a challenging synthetic target. An alternative route to its indolo[2,3-b]quinolone core structure involving a N-chlorosuccinimde-mediated intramolecular cyclization reaction is reported. Attempts to progress towards the natural product are also discussed with an unexpected deep-seated rearrangement of the core structure occurring during an attempted iodoetherification reaction. X-ray crystallographic analysis provides important analytical confirmation of assigned structures.

Synergy effect of electronic characteristics and spatial configurations of electron donors on photovoltaic performance of organic dyes

Considering the key role of electron donors to the intramolecular charge transfer of organic dyes, molecular arrangement and electron processes in dye-sensitized solar cells, four organic dyes (LI-133-136) were designed and synthesized with indolo[3,2-b]indole (IDID) as the main electron donor and various aromatics as the assistant ones. The broad light response was achieved by the strong electron-donating ability of IDID with a planar structure, and with the aid of the electron-rich property of carbazole and triphenylamine. Moreover, the twisted configuration and large size of triphenylamine on the head of dye LI-136 can be beneficial to suppressing dye aggregation and electron recombination, contributing to the improved photovoltaic performance. With the systematic investigation of their photophysical and electrochemical impedance properties, together with theoretical calculations, the electronic characteristics of IDID and the spatial configuration of triphenylamine were highlighted as a synergy effect on the photovoltaic performance, affording an efficient strategy to simultaneously enhance the light-harvesting property and suppress the charge recombination.
