Description

General description

Selectively protected building block for library synthesis or the preparation of γ-glutamyl peptides by Fmoc SPPS. After condensation of the side-chain carboxy with an appropriate amine or alcohol, the γ-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, amides, lactams and lactones containing the glutamyl unit.
