Problems were encountered during attempts to prepare N-terminal cysteine-substituted peptide nucleic acids (PNAs) from commercially available, Fmoc-protected monomers. These problems have been surmounted by the use of an S-t-butylmercapto protecting group on the cysteine moiety. The solid-phase syntheses are carried out via a simplified procedure which should be generally useful for manual PNA synthesis.
在尝试从市售的Fmoc保护的单体制备N端半胱氨酸取代的肽核酸（PNA）的过程中遇到了问题。通过在半胱氨酸部分使用S-叔丁基巯基保护基团克服了这些问题。固相合成通过简化的程序进行，该程序通常可用于手动PNA合成。
