Protected Amino Acid Active Esters Incorporating the 4-Picolyl Basic Solubilizing Group

Stewart, Frederick H. C.

, p. 2013 - 2017 (2007/10/02)

The 4-picolyl ester of 4-hydroxy-3-nitrophenylacetic acid has been prepared from an active polyester intermediate, and used as the precursor of a series of protected amino acid active esters.These compounds were satifactory coupling components in peptide syntheses.Purification of the protected peptides by acid washing was facilitated by the presence of the basic 4-picolyl moiety.
