title: Indium-Catalyzed [2 + 2] Cycloaddition of Allylsilanes to Internal Alkynones.
abstract: We have developed an indium-catalyzed [2 + 2] cycloaddition of allylsilanes to alkynones leading to selective cyclobutenone formation. The resulting cyclobutenones were readily converted to the oxidized products by Tamao-Fleming oxidation or the ring-opened products by an electrocyclic reaction.
