Synthesis of optically active lipopeptide analogs from the outer membrane of Escherichia coli.

The synthesis of optically active lipopeptide derivatives has been accomplished by the use of chiral glycerol derivatives. Lipopeptide derivatives with (R)-glycerol moieties showed higher mitogenic activities than those with the (S)-configuration. N-2,2,2-Trichloroethoxycarbonyl lipopeptide derivatives increased mitogenic activity.
