Synthesis of α‐thiophenylglycine peptides

Abstract
The synthesis of peptides useful for the investigation of microbial peptide transport is reported. These peptides, L‐alanyl‐L‐2‐thiophenylglycine (Ala‐α‐TPG), L‐alanyl‐L‐2‐thiophenylglycyl‐L‐alanine (Ala‐α‐TPG‐Ala) and L‐alanyl‐L‐alanyl‐L‐2‐thiophenylglycine (Ala‐Ala‐α‐TPG), contain a phenylthio group attached to the α carbon of glycine.
