Fmoc-Succinimide

Fmoc-Succinimide (Fmoc-OSu) is a mixed carbamate reagent for the selective preparation of N-(9-fluorenylmethoxycarbonyl) derivatives of hydroxyamino acids and hydroxyamino acid esters in high yields. Fmoc-OSu is a more preferable alternative to the use of the chloroformate, Fmoc-Cl, because it eliminates the formation of dipeptides. Fmoc-OSu has also been employed in the synthesis of glycopeptides.Formal Name: 2,5-dioxo-1-pyrrolidinyl 9H-fluoren-9-ylmethyl ester-carbonic acid. CAS Number: 82911-69-1.
