Popis: The synthesis of three thiophene analogues of Flosulide – a potent and selective inhibitor of cyclooxygenase subtype 2 (COX-2) – is described. Utilizing combined Friedel-Crafts acylation and alkylation of 2-chlorothiophene, simplified procedures were developed to obtain cyclopenta[b]- thiophenones as key products which were further derivatized by nitration, nucleophilic aromatic substitution, reduction, and mesylation.
