A prototype of benzobis(imidazolium)-embedded conjugated polyelectrolyte: synthesis by direct C?H arylation and fluorescent responses to anions

We report the convenient synthesis of a benzobis(imidazolium)-embedded conjugated polyelectrolyte pBBI by a Cu-catalyzed direct C?H arylation of a cationic benzobis(imidazolium) monomer with a diiodide comonomer. pBBI shows weak fluorescence in solution due to rotation of the repeat units in the conjugated backbone, and enhanced fluorescence when electrostatically interacting with a variety of anions to form aggregates. Specially, pBBI responds to the bisulfite anion with intensified unique deep-blue fluorescence easily discriminated by naked eye.

A tandem Friedel-Crafts based method for the construction of a tricyclic pyrroloquinoline skeleton and its application in the synthesis of ammosamide B

A total synthesis of ammosamide B (2), a member of the pyrroloquinoline alkaloid family isolated from marine Streptomyces, is described. The characteristic core tricyclic structure of 2 was constructed using a novel, tandem Friedel-Crafts reaction sequence to transform the symmetric tetra-amino substituted benzene derivative 7 into the tricyclic pyrroloquinoline product 8, which serves as an important intermediate in the route to the synthesis of the target natural product.
