The mannite derivatives have the formula (1) wherein R' and R.sup.2, idenal or different, represent when they are identical a straight or branched alkyl, alkenyl or alkynyl group containing from 5 to 24 atoms of carbon which may be substituted by a cycloalkyl residue having from 3 to 6 atoms of carbon, an aryl, benzyloxy, allyloxy, mesyloxy residue and/or halogen atoms and when R' and R.sup.2 are different, they represent a straight or branched alkyl group with 1 to 24 atoms or carbon, which may be substituted by a cycloalkyl residue having from 3 to 6 atoms of carbon, an aryl, benzyloxy, allyloxy, mesyloxy residue and/or halogen atoms, with the possibility for R' of being also a trityl group. From said mannite derivatives, it is possible to obtain in a simple way and with good yields the phospholipids in the form of their optical stereo isomers. ##STR1##
Glycerol derivatives of the general formula II, III or IV ##STR46## wherein when R.sup.1 and R.sup.2 are the same, they signify a substituted or unsubstituted straight-chained or branched alkyl, alkenyl or alkynyl group with 6 to 24 carbon atoms, the substituents being cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, and
Glycerol derivatives of the general formula II, III or IV ##STR48## wherein R.sup.1 and R.sup.2 are the same or different and, when R.sup.1 and R.sup.2 are the same, signify a substituted or unsubstituted straight-chained or branched alkyl, alkenyl or alkynyl group with 6 to 24 carbon atoms, the substituents being cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, and when R.sup.1 and R.sup.2 are different signify a substituted or unsubstituted straight-chain or branched alkyl group with 1 to 24 carbon atoms, the substituents being cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, or substituted or unsubstituted cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents,
Glycerol derivatives of the formula ##STR50## wherein R.sup.1 and R.sup.2 are the same or different and, when R.sup.1 and R.sup.2 are the same, signify a substituted or unsubstituted straight-chain or branched alkyl, alkenyl or alkynyl group with 6 to 24 carbon atons, the substituents being cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, and when R.sup.1 and R.sup.2 are different signify a substituted or unsubstituted straight-chain or branched alkyl group with 1 to 24 carbon atoms, the substituents being cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, or substituted or unsubstituted cycloalkyl radicals with 3 to 6 carbon atoms, aryl radicals, benzyloxy, allyloxy, mesyloxy and/or halogen substituents, and R.sup.1 can also be trityl
