When we discuss the total synthesis of lanthipeptides, we are often looking at the integration of non-proteinogenic amino acids, such as lanthionine or methyllanthionine. My interest in this field began with the study of Lacticin 481 and Lactocin S. The lantibiotic class is defined by these characteristic thioether bridges, which require highly robust solid-phase strategies.
Through my review of current literature, it is evident that the solid-phase total synthesis of these molecules relies heavily on Fmoc-based chemistry. The ability to perform peptide cyclizations on a solid support allows for the iterative addition of amino acids while managing the complex protective group strategies required for cross-linking.

Personal Perspective on Methodology
I find that the transition from solution-phase to solid-phase has significantly lowered the barrier to exploring new peptide analogues. When evaluating the solid-phase total synthesis of nisin or related structures, the repeatability offered by solid-supported chemistry is a major advantage. It allows for a more standardized approach to the total synthesis of complex macrocycles, ensuring that the lantibiotic analogues created retain the necessary structural motifs for their intended study.
