General description

Selectively protected building block for library synthesis or the preparation of β-aspartyl peptides. After condensation of the side-chain carboxy with an appropriate amine or alcohol, the α-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.

The product number for this product was previously 04-12-1080.
