Beschreibung

General description

Barany′s aminomethyl-dimethoxyphenoxyvaleric acid linker . The amino group of this linker can be easily acylated under standard coupling conditions. Following peptide assembly, treatment with 95% TFA containing scavengers releases the desired peptide amide. Studies have shown the acid sensitivity of this linker to be around twice that of the Rink amide linker. There is some evidence to suggest that PAL resins give greater yields in microwave assisted synthesis.
