We have developed a protocol for catalyst- and additive-free α-alkylationreactions of glycine derivatives with diacyl peroxides, which proceed by a pathway involving addition of alkyl radicals to imine intermediates. The diacyl peroxide substrate acts as both alkylation agent and oxidizing agent, which means it is atom-economical. It was applied to various glycine derivatives, dipeptides, and a 3

electrochemical cross-coupling hydrogen-evolution chemistryinvolving glycine amides and diarylphosphine oxides. A broad range of biologically active α-aminophosphonates was obtained in moderate to good yields in a clean and sustainable manner. Moreover, the TBAB (tetrabutylammonium bromide) electrolyte was recycled four times without obvious loss of reaction activity. Moreover, this protocol was performed
An organo-photoredox catalyzed gem-difluoroallylation of glycine with α-trifluoromethyl alkenes via direct C(sp3)–H functionalization of glycine and C–F bond activation of α-trifluoromethyl alkenes has been described. As a consequence, a broad range of gem-difluoroalkene-containing unnatural amino acids are afforded in moderate to excellent yields. This reaction exhibits multiple merits such as readily
