description
2-nitroveratryl (oNv) is a new orthogonal group which is compatible with SPPS protocols and that can be cleaved by photolysis (350 nm) under ambient conditions. In combination with complementary S-pyridinesulfenyl activation, disulfide bonds are formed rapidly in situ. In order to demonstrate the versatility of this approach, it was applied to the synthesis of a number of model peptides: oxytocin, alpha-conotoxin ImI, and human insulin.
