  Reactions of alpha,beta -dehydrodipeptides containing a terminal gamma -aminobutyric acid residue with 3-ethoxycarbonylbenzotriazole I-oxide at 90-100 degreesC result mainly in cleavage of the peptide bond. In the cold, the corresponding ethyl ester and N-acyl-gamma -butyrolactam are formed. Analogous reactions with N-benzoyl- and N-benzyloxycarbonyl-gamma -aminobutyric acids leads to formation of the corresponding ethyl esters.

  Comprehensive SummaryCompared to well‐established 1,5‐HAT of N‐centered radicals, the synthetic applications of 1,2‐HAT process were scarce due to the high barrier and constrained three‐membered transition state. Here, we have developed a novel C(sp3)‐H gem‐difluoroallylation via a base assisted formal 1,2‐HAT of amidyl radicals with the reductive quenching cycle of photocatalyst. This transformation enables the efficient formation of α‐aminoalkyl radicals via 1,2‐HAT and showcases good functional group tolerance. Our preliminary mechanistic experiments, along with Density Functional Theory (DFT) calculations demonstrate the feasibility of 1,2‐HAT of amidyl radicals, especially when assisted by a base. Furthermore, our method also succeeds in the Giese addition of electron‐deficient alkenes as well as styrene.
