Date Feb. 2, 1984.The mannite derivatives have the formula (1) wherein R' and R2, identical 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 R2 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. <IMAGE> (I) |
