Palladium-catalyzed highly regioselective [3 + 2] cycloaddition reactions of alkylidenecyclopropa[b]naphthalenes with alkenes or alkynes: an efficient synthesis of 1(3)-alkylidene-2,3-dihydro-1H-benzo[f]indenes and 1-alkylidene-1H-benzo[f]indenes.
The first palladium-catalyzed highly regioselective [3 + 2] cycloaddition reactions of alkylidenecyclopropa[b]naphthalenes 1 with alkenes or alkynes is presented, providing an efficient method for the synthesis of 1(3)-alkylidene-2,3-dihydro-1H-benzo[f]indenes or 1-alkylidene-1H-benzo[f]indenes under mild conditions.
