Draw the mechanism of the following reaction, including all intermediate steps: Cleaving the peptide backbone at...
Propose a synthesis, accounting for all reagents and steps, of the following peptide. Include a mechanism for the formation of each intermediate (if a step is repeated, the mechanism only needs to be shown once; no mechanism is expected for catalytic hydrogenation – if used). HN HINN Li Low ZI
