-S-(-)-1.1'-Diphenyl-2,2'-dinilro-6,6'-dicarboxylic acid (1) is used as an axial-chiral protecting group for the primary hydroxy group of glycerol and glyocerol derivatives. Diesters of 1 were formed which have the largest distance between the nitro groups and the nucleophilic subtituents on glycerol After hydrogenolytical removal of the protecting group asymmetric glycerol derivatives were obtained
