Regioselective Sulfonylvinylation of the Unactivated C(sp3)–H Bond via a C-Centered Radical-Mediated Hydrogen Atom Transfer (HAT) Process
摘要:
Given the similarity of multiple sp(3) C-H bonds in electronic properties and bond dissociation energy (DE), regioselective sp(3) C-H bond functionalization remains a paramount challenge. Here, we report a C-centered radical-mediated approach for site-specific sulfonylvinylation of the C(sp(3))-H bond via the hydrogen atom transfer (HAT) process. The reaction features mild conditions, broad substrate scope, and high regioselectivity and stereoselectivity, manifesting the nontrivial synthetic potential.
