A palladium-catalyzed [2π + 2σ] cycloaddition of vinyl bicyclo[1.1.0]butanes with methyleneindolinones has been developed. The reaction enables the construction spirobicyclo[2.1.1]hexanes bearing an all-carbon quaternary center in moderate to good yields excellent diastereoselectivities. This method features a broad substrate scope functional group compatibility. practical utility this protocol was further demonstrated by gram-scale synthesis and postsynthetic transformations desired product.
