description
Building blocks for aqueous solid-phase peptide synthesis (ASPPS). The 2,7-disulfo-9-fluorenylmethoxycarbonyl (Smoc) protecting group allows peptide synthesis using water instead of organic solvents – finally combining sustainability with cost optimization. The building blocks possess significant stability in basic aqueous solutions, but are easily losing their amino terminal protection upon mild treatment with particular water-soluble bases, e.g. NaOH, NH3, piperazine or ethanolamine. For ASPPS, a water-compatible resin, e.g. Tentagel, ChemMatrix, is required.
