Abstract A convenient and high-yielding synthesis of unsymmetrical dibenzothiophenes has been achieved by an acid-mediated ring closure of the biphenyl ring having a sulfoxide substituent at the ortho position. Various functional groups are well tolerated in this methodology. Keywords: Cyclizationdibenzothiopheneintramolecularsulfoxide ACKNOWLEDGMENT We are thankful to the Zydus Group management for encouragement and the analytical department for support.
