Amino acids and peptides. III. Synthesis of stereoisomeric alanine containing peptide derivatives and their effects on germination of Bacillus thiaminolyticus spores. 2.
Stereoisomeric alanine containing peptides were synthesized to study not only the relationship between the structure of alanine containing peptides and their effects on germination of Bacillus thiaminolyticus spores but also their antibacterial activity. The peptides obtained did not show any effect on germination. They did not exhibit any antibacterial activity against Staphylococcus aureus, Sarcina lutea, Pseudomonas aeruginosa and Escherichia coli.

Z-Protected diphenyl (decarboxy-dipeptidyl)phosphonates 5a-c with a (decarboxysarcosinyl)phosphonate moiety are prepared from Z-L-alanine (1a). Z-L-valine (1b), and Z-L-phenylalanine (1c) by the following series of steps: coupling with methyl sarcosinate (2a–c), saponification (3a–c), Hofer-Moest oxidative decarboxyiation by electrolysis in MeOH (4a–c), and Arbuzov reaction with P(OPh)3/TiCl4 (Scheme
