A New Synthesis of Benzothiophenes and Benzothiophenes by Annulation of Disubstituted Thiophenes

Nine newly prepared ortho-disubtituted thiophenes (1-5) react with Michael acceptors to form benzo- and benzothiophenes.This novel annulation process is specifically suited to form benzothiophenes with substituents in the benzene moiety.Substitution

SYNTHESIS OF QUINOLINE AND BENZOTHIOPHENE DERIVATIVES BY RING ANNELATION OF PYRIDINES AND THIOPHENES

Selected ortho-disubstituted pyridines and thiophenes react with Michael acceptors to give functionalized quinolines or benzothiophenes, respectively.
