Analytical and spectral data indicated the bacterial liposmino acids to be amino acid esters of phosphatidyl glycerol of the type (XI)(l-3), leaving unsettled the position of the amino acid residue and the configuration of the phosphatidyl glycerol moiety. Recently two syntheses of compounds of type XI were reported. Since both syntheses afforded only partly or completely racemic compounds (g,'lO), the problem of the structure and configuration of ...
