Silver hexafluoroantimonate-catalyzed three-component [2+2+1]cycloadditions of allenoates, dual activated olefins, and isocyanides
The intermolecular [2+2+1]multicomponent cycloadditions from readily available allenoates, dual activated olefins and isocyanides catalyzed by silver hexafluoroantimonate were studied. This protocol allowed the syntheses of highly functionalized five-membered carbocycles with exclusive regioselectivity and stereoselectivity in an efficient and atom-economical manner.
