Keywords: 5-Arylfuran-2-carboxaldehydes | 2-formylfuro[3 | 2-b]pyrrole-5-carboxylates | 2-formylfuro[2 | 3-b]pyrrole-5-carboxylate | benzothiazolium salts | 1H- and 13C-NMR spectra.
A series of new push-pull compounds were synthesised by reaction of 5-aryl- furan-2-carboxaldehydes and furo[b]pyrrole type aldehydes with benzothiazolium salts. These new condensation products represent highly conjugated systems that have potential biological activity. The reaction of furo[b]pyrrole type aldehydes with benzothiazolium salts give potential precursors of cyanine dyes.
