Synthesis of 4-substituted DBT from DBTO via a one-pot C-H boration-Suzuki coupling-sulfoxide reduction cascade process
Organic and Biomolecular Chemistry(2023)
摘要
A sulfoxide directed C-H metalation/boration/B2Pin2 mediated reduction/Suzuki coupling process to synthesize 4-substituted dibenzothiophene (DBT) in one-pot from dibenzothiophene-5-oxide (DBTO) was developed. A variety of DBT-based heterobiaryls were prepared in satisfactory to good yields. A mechanism was proposed. The application of this methodology was demonstrated by synthesizing a luminescent material.
