A formal [8 + 3]-cycloaddition, of enoldiazoacetates with donor acceptor cyclopropanes was realized by the Combination of a Lewis acid-catalyzed diastereoselective [3 + 2]-cycloaddition and a subsequent rhodium-catalyzed chemoselective ring expansion. This tandem transformation provides an efficient approach to highly functionalized cyclohexenes.
