N-O Dual Functional Group Transposition via Energy Transfer Photocatalysis. [PDF]

open access: yesAdv Sci (Weinh)
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

Catalysis of Hydrazone and Oxime Peptide Ligation by Arginine [PDF]

open access: yes, 2020
Hydrazone and oxime peptide ligations are catalyzed by arginine. The catalysis is assisted intramolecularly by the side-chain guanidinium group. Hydrazone ligation in the presence of arginine proceeds efficiently in phosphate buffer at neutral pH but is ...
