Chemical Mechanisms of Prebiotic Chirality Amplification

Figure 1

Asymmetric autocatalytic processes, where A is the substrate, B is the reactant, C is the catalyst, and P is the chiral product (a). Autocatalytic asymmetric diethylzinc addition to pyrimidine-5-carbaldehyde (the Soai reaction) with amplification of enantiomeric excess (b). Relationship between the enantiomeric purity of the initial catalyst and of the newly formed product in the Soai reaction, according to Ref. [19] (c).
