Solid-phase peptide synthesis provides a robust framework for assembling amino acids sequentially on an insoluble polymer support, commonly referred to as a resin. This approach simplifies purification by allowing excess reagents and byproducts to be washed away after each coupling step. Both the Boc (tert-butyloxycarbonyl) and Fmoc (9-fluorenylmethyloxycarbonyl) strategies are widely employed in SPPS, offering different deprotection chemistries suitable for various peptide sequences and desired modifications. The Fmoc/tBu strategy is particularly prevalent for its mild deprotection conditions, which are compatible with a wide range of functional groups.
