So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Gus’kov, V. Yu.; Gainullina, Yu. Yu.; Uteeva, Zh. D.; Musabirov, D.

Abstract: A chiral stationary phase is proposed on the basis of 3,4,9,10-perylenetetracarboxylic acid (3,4,9,10-perylentetracarbonacid, PTCA). The PTCA mol. itself is not chiral; however, it can form chiral supramol. structures. Symmetry breaking during the self-assembly of PTCA supramol. structures was carried out similarly to the Viedma ripening process. The obtained stationary phases with PTCA multilayers on an inert solid support and C18 silica were used to sep. racemates in gas and liquid chromatog., resp. It was found that the proposed stationary phases exhibit enantioselectivity with respect to pairs of enantiomers bearing a hydroxyl group at an asym. carbon atom. Enantiomers of butanol-2, pentanol-2, and 1-methoxy-propanol-2 were separated by gas chromatog. The separation of menthols was achieved in the normal-phase HPLC mode. It was shown that the separation of the last named compounds is possible up to a concentration of 0.04 mg/mL inclusive.
