β¦ Synopsis
Boc/'Z-protected PNA oligomers were synthesised on solid phase. The use of the allylic HYCRON resin allowed for the application of both Boc-and Fmoc-protecting groups. Highest yields were obtained when the monomeric building block was synthesised on solid phase rather than loaded as preformed unit. The selective attachment of fluorescent labels at the C-terminal (3') end demonstrated for the fast time that further manipulations on protected PNA fragments are feasible.
