Wangresin The development of Merrifield peptide resin by R. Bruce Merrifield revolutionized organic synthesis, particularly in the field of peptide chemistry. This innovative resin, a cornerstone of solid-phase peptide synthesis (SPPS), has maintained its significance due to its robust nature and versatility. For decades, it served as the standard support for the synthesis of peptides, especially through the Boc strategy. Understanding the properties and applications of Merrifield resin is crucial for researchers and chemists engaged in peptide and amino acid research.

Merrifield resin, chemically known as chloromethylpolystyrene, is a cross-linked polystyrene bead onto which a chloromethyl functional group is attached. This functional group is the key to its utility. It allows for the covalent attachment of the first amino acid in a chain to the solid support. The process typically involves the nucleophilic displacement of the chlorine atom. This immobilization onto the resin is a critical step, as it allows the growing amino acid chain to be retained during filtration, while reagents and by-products of the synthesis can be easily washed away. This is the fundamental principle behind peptide is 'immobilised' onto the solid-phase.

The degree of cross-linking, typically 2% cross-linked with divinylbenzene (DVB), influences the swelling properties and stability of the resin in different solvents. While 2% cross-linked is common, other levels like 1-2% divinylbenzene (DVB) are also utilized. This specific composition, poly(p-(chloromethyl)styrene-co-divinylbenzene) (Merrifield resin), provides a stable yet adaptable platform for chemical reactions.Seplife® Chloromethyl Resin (Merrifield resin) is the standard support for the Solid Phase Peptide Synthesis (SPPS) of acid peptides by Boc strategy.

The direct attachment of protected amino acids to the Merrifield resin marked a significant advancement, laying the groundwork for automated synthesis2016年9月27日—One of the most disruptive and fertile new ideas was organic synthesis on solid supports, developed by BruceMerrifieldin the early 1960s.. Bruce Merrifield's groundbreaking work on organic synthesis on solid supports, for which he was awarded the Nobel Prize, demonstrated the power of this approach. This method truly made it easy to get high-quality results in peptide synthesis.

While newer resins have emerged, such as Wang resin and others offering different cleavage conditions or functionalizations, Merrifield resin continues to be a relevant tool, especially when specific reaction chemistries are required or for historical method replication. Its robustness makes it suitable for demanding synthesis protocols.Aldrich-449113;Merrifield′s peptide resin 200-400 mesh, extent of labeling: 2.0-2.5 mmol/g Cl- loading, 2% cross-linked; CAS Number: 55844-94-5; ... For example, Merrifield resin can be derived from precursors like 2-Chlorotrityl Chloride (2-CTC) resin through specific activation processes, though the Merrifield resin itself is often the starting point.Resins for Solid Phase Peptide Synthesis (Part 2)

It can also serve as a support for immobilizing other molecules, such as catalysts or reagents. For instance, there are studies involving Ruthenium porphyrin bound to a Merrifield resin as a heterogeneous catalyst for cyclooligomerization reactions. This highlights the broader applicability of the resin as a solid support in various chemical processes. The ability to immobilize carboxylic acids and alcohols further expands its utility in the solid-phase synthesis of diverse organic compounds.
