   Enantiopure:

   Compound having one chirality in the molecule.

   Optically pure compound

   It interact differently with two enantiomers.

   e.g.

   *N-trifluoroacetyl-L-prolyl chloride)  for optically active amines,

                                                  e.g. amphetamines.

   *1-R-(-) menthylchloroformate          for optically active alcohols.

   Diasteriomers:

   Compounds having more than one chiral center and are not mirror
   image.
   They have same chemical properties but different physical properties.

                                                                          260
