some extent. The Sonogashira products obtained from the 4-bromophenylacetylene were allowed to react with functionalized benzo[b]thiophenes under C−C or C−N palladium-catalyzedcross-coupling conditions. Preliminary fluorescence studies were performed for mono- and disubstituted (4-aminophenyl)acetylenic dehydroamino acids and for the benzo[b]thiophene derivatives. The results showed that some of the
