We have established an efficient ruthenium(II) and iodine anion cocatalyzed dihalogenation cascade cyclization of internal alkyne-tethered cyclohexadienones, which stereoselectively afforded numerous products with a bioactive hydrobenzofuran skeleton in high yields under mild conditions. In this transformation, the reaction pathway was determined by concentration electrophilic reagent, also provided strategy for control selectivity. Furthermore, method features use 1,2-dihaloroethane as halogen source via catalyst.

Rhodium(I)-catalyzed asymmetric cascade reactions have emerged as powerful tools in contemporary organic synthesis, enabling efficient construction of complex molecular architectures. These transformations proceed through organorhodium intermediates, which undergo additions to reactive π-bonds, subsequently triggering with neighboring functional groups effectively forge multiple carbon-carbon bonds and stereogenic centers a single step under mild conditions. This article reviews the pioneering developments recent breakthroughs from 2002 2024, highlighting attractive advantages rhodium(I)-catalyzed their profound impacts on synthetic chemistry.
