UnverifiedChiral molecules are two molecules that are mirror images of each other, symmetrical in structure yet unable to be superimposed.66% similarPartially VerifiedSoai developed asymmetric autocatalytic reactions, in which the reaction product itself acts as its own catalyst, capable of amplifying a tiny chiral bias starting from achiral raw materials.61% similarUnverifiedKagan proposed that two or more chiral ligands can simultaneously bind to a metal to form a catalyst, and when the activity of the heterochiral complex is far lower than that of other types, the ratio of product enantiomers will exceed the ratio of the catalyst itself—a phenomenon known as the positive nonlinear effect.58% similarUnverifiedThe Soai reaction is an addition reaction between pyridine-5-carbaldehyde and diisopropylzinc, with an amplification factor as high as 630,000-fold; the product is a chiral secondary alcohol that can catalyze the next round of reaction, forming an autocatalytic cycle.55% similarUnverifiedIn 2003, Soai established the SOAI reaction system, generating chiral molecules from completely achiral starting materials, with the product self-replicating and the enantiomeric excess reaching as high as 99%.55% similar
