一般描述

Selectively protected building block for library synthesis or the preparation of β-aspartyl peptides by Fmoc SPPS. After condensation of the side-chain carboxy with an appropriate amine or alcohol, the β-amino and carboxy functions can be selectively unmasked with 20% piperidine in DMF and 50% TFA in DCM respectively, facilitating the synthesis of branched esters and amides, and lactams and lactones containing the aspartyl unit.
