Soai 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.

UnverifiedIf the product is also chiral and preferentially catalyzes the formation of molecules with the same chirality as itself, this constitutes chiral autocatalysis.78% similarUnverifiedThe Soai reaction demonstrates an autocatalytic phenomenon in which the reaction product itself can act as a catalyst to promote its own formation, and an initial ee value of only 2% can climb to above 87% after multiple rounds of autocatalytic cycles.76% similarUnverifiedAsymmetric catalysis is one of the most effective strategies for obtaining single enantiomers in modern organic synthesis, and can be divided into three major categories: enzymatic catalysis, metal catalysis and organocatalysis by small organic molecules, with advantages such as high atom economy, few steps and little waste.74% 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.73% 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.71% similar
