Abstract

The TBPB promoted tandem oxidative C(sp3)–H bond functionalization of simple alkanes/alkylation-initiated dearomatization of N-phenyl-cinnamamides is reported, providing a direct method for the synthesis of alkylated 1-azaspiro[4.5]decanes with excellent regioselectivity and diastereoselectivity. The formation of two C(sp3)–C(sp3) bonds and construction of a spirodienone motif are involved in one step.
