FeĢcourt, Fabien Delpech, Bernard Melnyk, Oleg Crich, David <i>Se</i>-(9-Fluorenylmethyl) Selenoesters; Preparation, Reactivity, and Use as Convenient Synthons for Selenoacids <i>Se</i>-(9-Fluorenylmethyl) selenoesters are readily prepared, stable precursors to selenocarboxylates, which they liberate on treatment with DBU. Fm selenoesters are compatible with the use of TFA for the removal of Boc groups and with simple peptide bond forming reactions. Amino acid derived selenocarboxylates condense directly with amines to give amides, react smoothly with isocyanates and isothiocyanates to give amides, and couple with electron-deficient azides also to give amides. selenocarboxylate;peptide bond;Fm selenoesters;Boc groups;Amino acid;amide;TFA;Convenient Synthons;DBU 2016-02-19
