Esters of N-(9-Fluorenylmethoxycarbonyl) Amino Acids with 4-Hydroxy-3-oxo-2,5-diphenyl-2,3-dihydrothiophene 1,1-Dioxide (Fmoc-Amino Acid TDO Esters) and Their Use in Solid Phase Peptide Synthesis

Fmoc-Amino acid TDO esters 3 are prepared by reaction of Fmoc-amino acids 1 with the cyclic carbonate 2.Their application in peptide synthesis is demonstrated by the preparation of leucylalanylvalylglycine (7) at a p-alkoxybenzyl alcohol resin.
