The synthesis of 1,2,3-trisubstituted cyclopenta[b]thiophenes was achieved through a Bronsted acid mediated dominoprocess under solvent-free conditions. In this one-potprocess, benzothienylation of 1,3-dicarbonyls follows an intramolecular aldol-type reaction leading to the generation of functionalized and highly substituted annulated benzothiophenes. This class of compounds find potential applications
