Abstract
The formation of a chirally pure prebiotic environment was modeled using solutions of chiral trifluoroacetylated amino alcohols (TFAAA). We have previously shown that, homochiral TFAAA solutions, molecularly thin strings are formed. In TFAAA-1 and TFAAA-5 solutions in heptane, the physicochemical annihilation of antipodes occurs, whereby isometric granules or a viscous liquid are formed from a racemic solution. In a heterochiral solution, the chiral polarization grows spontaneously, so that its chiral purity becomes high enough to produce TFAAA homochiral strings. A racemic solution of TFAAA-6 in CCl4 forms TFAAA homochiral strings of two opposite chiralities; i.e., the separation of the isomers takes place. It demonstrated two possible scenarios for the formation of a chirally pure system.
