Metal-free decarboxylative C(sp3)–C(sp3) bond formation for the synthesis of unnatural amino acids and peptides via convergent paired electrolysis enabled radical–radical cross-coupling

Herein, we present the first metal-free decarboxylative C(sp 3 )–C(sp 3 ) cross-coupling of glycine derivatives with redox-active esters through highly atom and energy economical convergent paired electrolysis enabled radical–radical cross-coupling.
