, p. 494 - 496 (1997)
The title compound, C7H4Br2O2, crystallizes as centrosymmetric dimers in which two molecules are linked by two hydrogen bonds between the hydroxyl and carbonyl groups, with an O···O distance of 2.839 (5) angstro

New tetrazole-fused π-conjugated molecules were prepared from dibromobenzonitriles by repeated regioselective Sonogashira-Hagihara cross-coupling with acetylenes and intramolecular nucleophilic cyclizations. The conjugated tetracyclic compounds exhibited fluorescence with lifetimes of nanosecond order. From TD-DFT calculations, excited state wavefunctions of compounds indicated that the HOMO-1→LUMO and HOMO→LUMO+1 mainly became the first excited state (S0→S1) to contribute significantly to light emission.

The natural product, convolutamine I (1), has anti-trypanosomal activity however it has a high molecular weight of 473 due to a presence of 3 bromine atoms. The synthesis of the natural product convolutamine I (1) together with its analogues are presented. A SAR study against Trypanosoma brucei brucei led to compounds with improved physico-chemical properties: lower molecular weight and lower log P while maintaining potency (with a slight 2-fold improvement).
