Chemical structure of Fmoc-Asp(OMpe)-OH

GA21537

Fmoc-Asp(OMpe)-OH

Also known as (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(3-methylpentan-3-yloxy)-4-oxobutanoic acid

The OMpe (O-3-methylpent-3-yl) side chain protecting group significantly reduces aspartimide formation, an undesired side-chain reaction encountered with the repetitive piperidine treatment needed for Fmoc removal
