                                All compounds are 2, 3- cis racemates , and were synthesized as described.

                                Additionally, the experiment produced racemates and not homochirality, which is utterly useless to any sort of possible life.

                                Eight single-isomer ammonium-β-cyclodextrin derivatives with different side chains were successfully developed as chiral selectors for the chiral separation of selected racemates in capillary electrophoresis.

                                Living organisms have special mechanisms to produce homochirality, but ordinary undirected chemistry, as in the hypothetical primordial soup, would produce equal mixtures of left and right-handed molecules, called racemates .

                                Subsequent studies of the racemates showed that the central stimulant activity is associated with the threo racemate and were focused on the separation and interconversion of the erythro isomer into the more active threo isomer.
