Chemical structure of Fmoc-Pra-OH

GA21782

Fmoc-Pra-OH

Also known as (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)pent-4-ynoic acid

Building block for the synthesis of precursor peptides for tritiation, and for "click chemistry"·Pra-containing peptides have been modified by 1,3-dipolar cycloaddition, e·g· with alkyl azides· Peptides containing a Pra residue and an α-azido acid have been cyclized in the presence of CuBr/Na-ascorbate via triazole formation· Educt for the synthesis of Phe-derivatives by rhodium-catalyzed [2+2+2] cycloaddition
