Three stereoisomers (cis-L, trans-D and cis-D) of N-Fmoc-glycyl-4-(thy
min-1-yl)proline and their pentafluorophenyl esters have been prepared
for use in the synthesis of novel peptide nucleic acids. In addition,
N-Fmoc-glycyl-4(N-6-benzoyladenin-9-yl)proline, N-Fmoc-glycyl-4-(N-4-
benzoylcytosin-1-yl)proline and N-Fmoc-glycyl-4-(N-2-isobutyrylguanin-
9-yl)proline and their pentafluorophenyl esters of the cis-D series ha
ve been synthesized.
