A facile synthesis of 7,8-di aryl coumarino and flavano benzo-thiophenes

The key step for the synthesis of 7-hydroxy 2,3-diarylsubstituted benzothiophenes 5a-f, by starting from substituted 2-aryl-2-((2-methoxy phenyl)thio)acetophenones 3a-f as an intermediate, consists of a Friedel-Crafts cyclization followed by demethylation by Lewis acids like BF3OEt2 and AlCl3 in DCM.
