Fmoc-Asp(2-phenylisopropyl ester)-OH
Also known as (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-4-oxo-4-(2-phenylpropan-2-yloxy)butanoic acid
An aspartic acid derivative allowing specific side chain deprotection with 1% TFA in dichloromethane· Ocampo et al· applied OPp protection during the synthesis of a peptide-oligonucleotide conjugate and cleaved it with 3% trichloroacetic acid in DCM·The OPp derivative is far less prone towards base-catalyzed aspartimide formation than the OAll, OBzl, or ODmab esters, its stability comes close to the stability of the OtBu ester
