UnverifiedIn 1953, Charles Frank proposed a model specifying three conditions: the reaction requires a chiral catalyst, the generation of one mirror-image molecule is enhanced while the other is suppressed, and the reaction can generate its own catalyst (autocatalysis).61% similarUnverifiedThe Soai reaction is the first and to date most exemplary experimental demonstration of asymmetric autocatalysis.61% similarUnverifiedThe Frank model demonstrates that if a chiral molecule can catalyze its own formation while inhibiting the formation of its mirror-image molecule, even an extremely minute initial difference in the ratio of the two chiral molecules will ultimately evolve into an almost purely single-chirality outcome.61% similarUnverifiedIn 1995, Soai Kenso published a breakthrough experiment using pyrimidyl alcohol to achieve asymmetric autocatalysis, in which the starting enantiomeric excess of one isomer was only 2%, and by the end of the reaction the enantiomeric excess had risen to 87%.58% similarUnverifiedThe 1953 Miller–Urey experiment successfully synthesized amino acids in the laboratory by simulating primitive atmospheric conditions, providing experimental support for the primordial soup hypothesis.58% similar
