The BINAP ligand-rhodium catalyst system developed by William Knowles can efficiently catalyze the hydrogenation of prochiral olefins, generating a single chiral product with extremely high enantioselectivity, and was applied to the industrial production of the Parkinson's disease drug L-DOPA.

UnverifiedThe Soai reaction was first reported in 1995, using an addition reaction between pyridinecarboxaldehyde and an organozinc reagent, in which the alcohol product can catalyze the next round of same-chirality product formation with extremely high efficiency.65% 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.65% 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% 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.61% similarUnverifiedThe Soai reaction uses pyrimidinyl aldehyde as the substrate to react with a dialkylzinc reagent to produce a chiral alcohol, which itself is the catalyst for the reaction, and its amplification mechanism is related to the fact that homochiral dimers are far more active than heterochiral dimers.60% similar
