Practical methodology is reported for the synthesis of a homologous series of sidechain extended amino acids containing aminooxy functionality bearing orthogonal protection suitable for Fmoc peptide synthesis. These reagents may be useful for the preparation of libraries containing fragments joined by peptide linkers.
peptides have attracted increasing interest because of their well-ordered secondary structures and stability toward enzymatic degradations. We have designed and synthesized nucleo aminooxy acids as novel building blocks for nucleopeptides. Four nucleo aminooxy acidderivatives with cytosine or thymine in the side chain linked by an amide or a triazole moiety have been synthesized from l-serine. Nucleobase-functionalized
