) bond activation of benzosilacyclobutene. This method exhibits a robust substrate scope, accommodating allenes with alkyl, alkenyl, aryl, silyl, alkoxy, and complex bioactive substituents to deliver enantioenriched functionalized silatetralins. Moreover, the protocol provides direct access to valuable exocyclic methylene-containing silatetralins, serving as versatile intermediates for further synthetic diversification.
