✦ Synopsis

Abstract

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.
