Efficient Synthesis of Unsymmetrical Dibenzothiophenes by Acid-Mediated Intramolecular Cyclization of Biaryl Methyl Sulfoxides
摘要:
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.
