Various terheterocyclic compounds containing thiophene, furan, selenophene, pyridine and thiazole rings have been obtained by the Pd(PPh3)4-catalyzed coupling of dihalo-substituted heterocyclic compounds with heterocyclic boronic acids, using sodium bicar

Several derivatives of 2,2':5',2''-terthiophene, 1a, and a structural analogue of this natural phototoxin, i.e. 5--2,2'-bithiophene, 2, have been conveniently synthesized on a medium scale using a general approach which involves palladium-catalyzed carbon-carbon bond forming reactions between (hetero)aryl halides and heteroaryl organometallics such as Grignard reagents, organozinc and organotin compounds.These 2,2':5',2''-terthiophene derivatives, which include some naturally-occurring compounds, have been characterized by EIMS spectrometry , 1H and 13C NMR spectroscopy as well as by absorption and fluorescence measurements.Four of these phototoxins exhibit considerable antibiotic and antiviral properties in the presence of UVA light and are cytotoxic against the P 815 mouse mastocytoma cell line.
