Article abstract of DOI:10.1021/jo4024478

Efficient construction of 2-sulfonylbenzo[b]furans is achieved from readily available trans-2-hydroxycinnamic acids and sodium sulfinates mediated by the CuCl2.2H2O/AgTFA system under mild conditions. This unprecedented synthetic protocol provides expedient access to a series of products in one step via a protodecarboxylation/C-S bond formation/C-O bond formation cascade.
