Preparation of an angiotensin i analog containing a p-phosphonomethyl-l-phenylalanine residue via asymmetric synthesis of t-boc-p- dimethylphosphonomethyl-l-phenylalanine
摘要:
t-BOC-p-Dimethylphosphonomethyl-L-phenylalanine has been prepared and incorporated into a peptide sequence corresponding to angiotensin I. Demethylation of the dimethylphosphonomethyl moiety then yielded a peptide containing a p-phosphonomethyl-L-phenylalanine residue.
Synthesis of p-Phosphonomethyl-L-phenylalanine using Camphor Sultam or D-Valine as Chiral Auxiliaries and its Incorporation into Integrin Sequences.
摘要:
The synthesis of N-Boc-p-phosphonomethyl-L-phenylalanine with two different chiral auxiliaries, camphor sultam or D-valine is described. The preparations have essentially identical properties and have been used to incorporate the amino acid into two integrin peptides as non-hydrolyzable isosteres of phosphotyrosine.
