Environmentally Conscious In-Water Peptide Synthesis Using Boc Strategy

Seeking a more environmentally balanced method of peptide synthesis, we are focusing on developing organic solvent-free synthetic methods using water, an environmentally friendly solvent. In current peptide synthesis, the most common building blocks are Boc- and Fmoc-protected amino acids, which are highly soluble in organic solvents. We previously reported a technique for solid-phase peptide synthesis in water that utilizes Fmoc-amino acids converted to water-dispersible nanoparticles. The Boc strategy is well-known to be suitable for the industrial chemistry and green chemistry, because only gases are generated without any other by-products in the deprotection step of Boc group. Here we summarize in-water both liquid and solid-phase method using Boc-amino acids based on MW-assisted coupling reaction of nanosized reactants, nanoparticles and nanomicelles.

Peptide synthesis 'in water' by a solution-phase method using water-dispersible nanoparticle Boc-amino acid

Regulatory pressure has compelled the chemical manufacturing industry to reduce the use of organic solvents in synthetic chemistry, and there is currently a strong focus on replacing these solvents with water. Here, we describe an efficient in-water solution-phase peptide synthesis method using Boc-amino acids. It is based on a coupling reaction utilizing suspended water-dispersible nanoparticle reactants. Using this method, peptides were obtained in good yield and with high purity.

O-(N-ACYLAMINOACYL)-2-PYRIDYLMETHYLKETOXIMES AND THEIR USE IN PEPTIDE SYNTHESIS

Preparation of Leu-enkephalin, Met-enkephalin and one analog of Leu-enkephalin by using O-(N-acylaminoacyl)-2-pyridylketoximes is described.Both the side products and the unreacted active amino acid derivatives were removed by utilizing the formation of a copper complex with 2-pyridylmethylketoxime.
