A one-pot method for the preparation of 2,5-diarylthiophene-1-oxides from arylacetylenes
Tetrahedron Letters(2016)
摘要
•2,5-Diarylthiophene-1-oxides bearing various functional groups were synthesized.•Provides access to substrates that were unattainable through oxidation strategies.•Yields are comparable to previously established multi-step oxidation strategies.•Thiophene-1-oxides are highly reactive Diels–Alder adducts.
