Copper/Silver-Mediated Cascade Reactions for the Construction of 2-Sulfonylbenzo[b]furans from trans-2-Hydroxycinnamic Acids and Sodium Sulfinates
摘要:
Efficient construction of 2-sulfonylbenzo[b]furans is achieved from readily available trans-2-hydroxycinnamic acids and sodium sulfinates mediated by the CuCl2 center dot 2H(2)O/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.

for the construction of significant functional methylsulfones, in which introduction of sulfur dioxide at the last stage was successfully achieved in one step. Inorganic sodium metabisulfite was used as an eco‐friendly sulfur dioxide source. Green dimethyl carbonate was employed as methyl reagent in this transformation. Diverse functional methylsulfones were obtained from various readily available
