Functionalized benzosultams are an essential class of structural motif found in various biologically active molecules. The synthesis of spirocyclic benzosultams from N-sulfonyl ketimine and alkylidenecyclopropanes (ACPs) under the catalysis of Rh(iii) has been developed. This transformation enables the formation of two C-C bonds and a double bond with high E-selectivity through C-H and C-C bond activation
