Base-controlled divergent synthesis of vinyl sulfones from (benzylsulfonyl)benzenes and paraformaldehyde?
Organic & Biomolecular Chemistry Pub Date: 2020-04-22 DOI: 10.1039/D0OB00362J
Abstract
A tuneable metal-free protocol for the selective preparation of α-substituted vinyl sulfone and (E)-vinyl sulfone derivatives has been described. In this process, stable paraformaldehyde was used as the carbon source. The base played an important role in the selectivity control of transformations. More than 50 products were synthesized with excellent chemoselectivity and broad functional group tolerance.
