While solution-phase synthesis has been explored, the advent and refinement of solid-phase peptide synthesis (SPPS) have revolutionized the field.The role of chemical synthesis in developing RiPP antibiotics SPPS, a method used to create peptides by assembling amino acids in a stepwise fashion on a solid support, such as a resin, offers significant advantages in terms of automation and purification compared to traditional solution-phase methods, which are typically very arduous and laborious.

One of the primary challenges in the total synthesis of nisin is the construction of its characteristic lanthionine (Lan) and methyllanthionine (MeLan) rings. These thioether bridges are crucial for nisin's biological activity and stability. Early strategies, such as the total synthesis of nisin by the Shiba group, employed desulfurization approaches to generate these bridges, followed by the condensation of peptide fragments. More contemporary research has focused on developing sophisticated SPPS strategies to incorporate these modified amino acids. For instance, studies have explored the solid-phase synthesis of nisin lipopeptide analogues using orthogonally protected lanthionines synthesized via ring-opening chemistry. This approach allows for the controlled formation of these complex linkages during the peptide synthesis process.
